How to Install the Rear View Safety Blind Spot Sensor System on a 2021 Chevrolet Colorado

Hi there, Chevy owners. Today at 2021 Chevrolet Colorado we're gonna be taking a look at and showing you how to install RVS's Blind Spot Monitoring System. So we've got our sensors installed. We're gonna go ahead and take it for a spin here and see what happens. So, first off, we're just gonna cruise through the parking lot real quick just to see how they react when we're just driving by objects. We can see we've got some cars on both the left and the right there, and you can see that the indicator lit up when we drove by.

We didn't get any audible sound from it because we don't have a turn indicator on, we're not intending on changing lanes or going in that direction. So there's no reason for it to give us an audible warning to let us know like, "Hey, pay attention before you do that." But it is illuminating, letting us know that, "Hey, the detection system is detecting an object." So we're just gonna swing back through there. So now we're ready to make a turn. And we've got a car on a right there and it beeped at us letting us know that that was in our detection range. We're gonna go ahead and make another turn here.

And again, it's beeping at us cause we have cars all on the right. A Blind Spot Monitoring System is designed to give us an extra warning for locations that we just don't have good visibility of. We do have side mirrors, rear view mirrors, and we can turn our heads to look around, but there's gonna be certain points where we're just gonna have the incorrect angle in our mirror, a pillar in our way next to us that we're just not gonna potentially see the car that's right there next to us towards the back of our vehicle. With a system like this, we're gonna get an audible warning as well as an indicator that's gonna let us know whenever we have vehicles near us so that we can appropriately change lanes safely. Now our customer today that purchased this, she actually works here at etrailer, and she is a bit of a shorter lady.

And she does mention that she has some difficulty seeing out of the window sometimes due to that. So adding this system in for her is gonna really help her out, ensure she can get to and from etrailer every day. So we're sitting here now, I've got my right turn signal on with a vehicle next to us, and you can hear that it's giving us the beep so we don't move. This chime is produced by a speaker that comes included with the kit. And on that speaker, it's gonna have three settings, you can turn it off if you just want the visible indicators that's installed, but you can also have a low or a high volume setting.

We've currently got it on the high setting. So that way it's gonna definitely wake us up. We don't wanna be driving home maybe late at night where we're kinda drowsing off, hit the turn signal. We want it to wake us up so we're prepared. You'll receive two sensors and two indicators in your kit. These are for the rear on both the driver and passenger side is that's the most important spot cause that's where you're gonna have the most blind spots. You're also gonna receive all the wiring that you need to get everything installed. We'll begin our installation at the back of our vehicle by determining where we wanna put the sensors. If you read the instructions, they want you to put it within 50 to 150 millimeters from the rear, and that puts us at pretty much right here at the front of where our bumper is. And we can mount it anywhere we want. And this location back here, as long as we're at least 500 millimeters from the ground. In inches, that's roughly 2 to 6 inches from the corner here's where our proper location should be. And at least 20 inches from the ground. Our truck sits up pretty high so we don't have to worry about that height measurement with this one, but we do need to make sure we really don't come past about where our bumper wraps around here cause that's would exceed the limits outlined in our instructions. And for that reason, we are gonna be using our bumper instead of the actual body of the vehicle to mount the sensor. We're gonna be putting it in the plastic right here at the front corner, cause if we feel around the backside, we can see that it's all plastic here, it's all open. So we shouldn't have any problem getting our sensor mounted up there. So I've gone ahead and marked one and a quarter inch down and one and a quarter inch over. We just did those measurements, so that way when we go to put the one on the other side, we can make it in the exact same location. So we'll use those measurements over there as well. You can use whatever measurements you want. You just wanna keep them in mind, so that way you can ensure the other side's in the same spot. This is your sensor right here. So we're gonna be using the larger hole saw that comes in our kit. You do get two hole saws, the larger one's for these sensors, the smaller one is for some lights we're gonna be putting on later. So we're gonna go ahead and drill through this and make our hole. You do wanna be careful when drilling through not to go too far to hit the body. So now we've got this side drilled out. We can just take a razor knife or you can even use your fingers here to peel off any of the rough edges. We'll then insert our sensor. If we look at our sensor on the back, you'll have a small arrow. That arrow is designed to point towards the rear of the vehicle. So we're gonna have it like this. It's pointing towards the rear. We'll just slide our wires through and then insert the sensor, just double-check that arrow one more time, we can see it's kinda pointing like just right at, maybe slightly below that little prong there. So that's how we wanna orient it to make sure we have that. And just press it into place. In the body, just behind the bumper where we drilled out for our sensor, there's already a pre existing hole there. So we just took the wire that's coming off the back of our sensor and poked it through that hole so we can make our connection on the other side, that'll help keep our wire hidden. So here we are underneath, you can see this is our sensor where we poked it through the hole and this is our harness where we're going to plug it in. We wanna make sure we've got number one. You can see they're labeled here. This just kinda slides on here. This is also the shorter piece of wire. The one with number two is much longer cause it goes over to the other side. Now, this does thread and plug directly into the sensor there. We want to take the adaptor that comes in our kit. This is to help reduce any noise and interference that you can get while running down the road. We don't want any false indications coming from passing by just some interference. So we're just going to plug these two together and then thread the two ends together. And then the other end of this is going to thread right into our sensor. We'll then repeat this over on the other side. The one labeled number two here, I just routed across the back of the bumper. I just followed the factory wiring harness. Whenever routing, wiring, it's always best to follow your factory harnesses cause they're already routed in a way that is going to ensure it's not going to hit anything excessively hot, like your exhaust or come into contact with any moving components, like your steering or suspension. And I just zip tie it to that factory harness as I'm making my trip. Once we get these plugged in, we'll route our wire up to the front where we'll start mounting up the module and making the rest of our connections. The rest of our harness we then routed towards the front. We go over top of the frame, hit our factory harness here and then just follow this factory harness all the way forward. We just zip tie it to this factory harness as we go along the way, you can see the zip ties. Once we hit our fuel tank here, we do pop over the frame and we did that cause our factory harness also goes up on top of the frame. We just keep following that factory harness all the way forward, just zip tying it along the way until we get right here to the front of the vehicle, right at the driver's door. Here's the front body mount. If we look right up in here, there's a grommet located just up from this location and you can see our grommet located right here. This is where we needed to get to. So now we need to go inside the vehicle cause we're gonna have to take our carpet up to be able to access this grommet. We've got our wire routed right here so we're ready to pull it through once we get to getting this grommet out. We're now inside the vehicle, we've opened up our door and we're gonna need to remove the trim panel that runs down the side here. So we're just getting our fingers underneath of it and just popping it up. And we just kinda pull it towards the rear and that'll get that panel out of there. We'll set it aside where it won't get damaged, then we'll pull our carpet up. There's some hooks that kinda is hooked on along here. So you just wanna use a screwdriver or something to pop it off of those hooks. And just keep popping it off the hooks until you can get underneath the terry. Just gonna have to keep on working it along the way. And that's our grommet right there. So we can use a screwdriver to pop it out of there. You can go from underneath and pop it straight up. Whichever way works best for you. Usually going from underneath and knocking it up is the easiest way, then push your wire through the hole. So now that we've got our wires run up to this location, it's gonna plug into our module box here, but we've got a lot of other wires to run still here inside of our cab. We've got more components to actually drill out and mount inside the cab as well. So to make things easier, we're just gonna start removing all the panels that are gonna be in our way. There's a lot of panels we're gonna have to remove, but most of them come off pretty easily. Your truck's gonna look pretty bare on the inside, but luckily most of them just pull right apart. For example, your "A" pillar. These need to come off on each side. And these literally just pull off. Just pull it out of there like that. On the other side there are two bolts that will be present if you have a handle on it, you just wanna remove those two bolts first, we'll go over there and show you how to get those bolts out. To remove the panel on this side, you'll access the bolts by removing the covers here. There's a small slit opening for a very small screwdriver to fit in. So just pop your screwdriver in there. You can kinda see the little extra opening for where the slit is, where your screwdriver fits in and then just pop those out of there. We can then remove the bolts with a 10 millimeter socket. And then once you've got both of those bolts out there, this side comes off just like the other side. Just gonna give it a good tug. And that'll pull off of there as well. Now we pulled those pillars off, cause we're gonna be mounting some lights in there, but we need wires to get to those lights as well. So in order to route wires up there, we're gonna pull off the trim piece here just between where you opened your door up on the side of your dash. These are just gonna pop off, just take a trim panel tool and stick it in there and just work your way down, pulling it off as you go. And then that'll just pull out of there as well. The other side comes off the same way. We'll also I need to remove the panel here just below the steering column. There's two bolts on bottom we'll remove with a seven millimeter socket. Once we have both bolts removed, the panel just pulls off of there. I like to start at the bottom corners first and then just kinda work my way up, just pulling towards the rear of the vehicle. Once you've got that pulled out, pull out on the red tabs located on the electrical connectors here. Then you can press in on those and get those disconnected. Now we've got this panel at least drooped down, it's okay to let it hang here by the parking brake cable, that's fine, it's not gonna be in our way too much, but this panel here behind it is. So we're gonna remove this with our 10 millimeter socket. There's four bolts that hold it on. So now we got everything off. Now it's actually just this panel. Once you've got all the bolts loose has some ears. You'll just need to lift up slightly and that'll pop off of there and we can set it aside as well. We now need to mount up our indicators. These are gonna go in the pillars that we had removed, and this is our indicator here. This is gonna use the smaller hole saw that comes in your kit. The red one's gonna be for our passenger side. So that's this one here. And the one with the black and white wire is gonna be for the driver's side. I've gone ahead and made my mark on each one. We're gonna try to put them in roughly the same location. So on the little tab that sticks out here, I marked the center of this tab. And then I measured up two inches from the bottom of the tab here. I did the same on each one, so that way we're gonna get roughly the same location. We'll then use our hole saw here and we'll drill this out. If you have any rough edges, you can clean those up just like we did before. We'll then take our sensor. We're gonna slide it through and then you can choose the orientation that you want. We're gonna make ours a triangle shape. So we're gonna put the flat edge of the triangle with the flat here at the bottom. And then we'll go ahead and insert the one over on the other side and the same way. After you've got it inserted, if you wanna twist it, you can kinda twist it somewhat in there. So now we can start routing our other harness. This other harness also plugs into your module. Coming off of it, you'll have several wires that we're gonna need to connect now. We're gonna start by routing the ones that are in the sheething here. It's kinda like a flat sheething. The shorter one is gonna route, we just went right up behind the panel here through the opening, and we just go right up here to our "A" pillar. This is gonna plug into the sensor that's on this side. The other wire that looks just like this, we're gonna route across. We went underneath our center console there till we came out the other side. And we basically just do the same thing. Once we run it underneath the dash over here on the passenger side, we'll go up through the opening that we had. That's exactly the same over here. This panel just pulls off. You can see here, everything's the same over here on this side, we just go up through the opening and bring it up. This wire is the longer of the two and it's also has the red wire. The other one had a little bit of white, so there's a slight color difference as well. And so now that we've got these wires routed over here, we can go ahead and plug these in. This is just gonna plug into the indicator that we put on here. There's a little lock tab there that lines up with the notch and they just click together just like that. We can then take our wire, the excess I'm just gonna poke back down here behind the dash. And then just re-install our panel in reverse order of how we removed it. We're gonna install the one on the other side as well. Plug in that electrical connector and put that panel back on. You can also re-install the other side panels that we had removed on the side of the dash, because we don't need to get up here anymore once we've got these installed. We're now located on the driver's side behind the metal panel that we'd removed, our body control module's located right behind this panel, little bit to the left of our steering column. We need to have both our left and right turn signal. So that way the system knows when we're turning to activate it. We can find these signals on the back of our body control module on the fourth and fifth connector. That's gonna be the black connector here as well as the brown connector right below it. Just peeling off some of the sheething here so we can better access our wires. We're gonna also do that to the one right below it here. It's just a little bit, you don't need to go crazy with it. We're gonna be quick splicing onto these. So we just wanna be careful to get that sheething off of there. Just enough to where we can get our quick splice on there. Now, as far as quick splices and making connections, your kit doesn't come with any. So I do highly recommend quick splices like we're gonna be using today. You can get those at etrailer here. So just add those to your cart before you check out. So here we've got our wire pulled out. This is on the black connector. This is pin number 3 here, looks like 3 if you count them down, and it's a green wire with a violet stripe, that's going to be the right turn signal. So we're gonna grab our harness now and coming off of your harness, you're gonna have a bunch of wires that look just like this. They are gonna be labeled for you. So that way you know which one goes where. So we're just gonna separate these out real quick. And the three wires we separated out are gonna be a brown, a violet, and a white. The right turn signal is our violet wire. So that's gonna connect to the green wire with the violet stripe. So we're just gonna use our quick splices to make that connection. So just take your quick splice, slide it over the factory wire. And then once you make sure that you've got that all the way inserted, we can then take our right turn signal wire. We're just gonna poke that in through the other hole. And then while holding it in that other hole, we are going to use a pair of pliers to squeeze the metal tab down here, which is going to connect both the two wires together. So we're just gonna slip this one through, take our pliers, make sure that we don't pinch any wires. Double-check your factory wire to make sure it's in its correct channel and then just squeeze it together there. And that's gonna connect these two together. We can take the lock tab, flip it over, lock it in place. And now we're just gonna perform the same procedure with the two remaining wires. I'll pull out the wire colors and then I'll show you which ones those were. For the remaining connections we took the brown wire here and hooked it to the blue wire with the white stripe. This is pin two on the brown connector that's just below the black one there. The white wire is for the dimming of our lights. So that way when we turn the headlights on, when it gets a signal on this, it's gonna dim our indicators, so that way it's not blinding us at night, we just hook this to one of the running light circuits so that way when lights are turned on, it'll dim those. And we just hooked it under the running light circuit located just below the passenger turn signal that we hooked up. So it's the black connector and we hooked it to the gray wire with the brown stripe. There's also a violet wire with a gray stripe right next to it. That one is also so you could choose that one as well. We just chose the gray and brown because it was a little bit easier to see in the connector and find that one. That way the signal will receive an input when your lights come on, this will dim them at night. Next we're gonna take our power wire, which is the red wire that's coming off of our harness here. This needs to be hooked to an accessory power. So that way it's only powered up when you turn the key on. We're gonna hook that to a fuse in the fuse box on the other side. You can see here how it's labeled "Accessory" on. It's not gonna be long enough to reach to one. So we did add some additional wire to it. If you need some additional wire, you can get some here at etrailer. We're gonna route it underneath to cross to the other side, just like we did with our other wire. The way I did that before was just used a little piece of electrical tape here and piece of fish wire. Fish wire can be really anything. If you're doing this at home, metal coat hangers work really well. We're using airline tube here. So we've got our wire routed over, our fuse box is located right here. There's a single knot that you can take off. It's a plastic knot, just pull it off and the cover just pulls right off. So we're gonna be hitting ours to fuse number 29. It's a 10 amp fuse located in this box. If you we're to look on the backside of the panel, you'll see on there the numbers. So we're just gonna go ahead and remove that. We're gonna use a pair of needle nose to do so. We're then gonna take that fuse and insert it into the bottom row of our fuse tap, and then we're gonna take another fuse and place it into the top on our fuse tap. The top is gonna be for our circuit that we're gonna be adding. You can get fuse taps here at etrailer. We're using this one here. And we wanna make sure that when we insert this into our fuse slot, that we insert it in this orientation, because we want this to be the hot leg and inside of our fuse box this is the hot leg. That way it's gonna travel up through our fuse and out our additional lead that we've added on here. Now, fuses don't come included with your kit, so you wanna make sure you also get a micro fuse, so you can have way to power up your new circuit cause you're just taking the old fuse you pulled out and putting it in here. And that keeps that fuse still active for that circuit. I recommend using a five amp fuse. We then just strip back the extension that we've made. If you're hooking it directly to the wire, it's already pre-stripped. And we're just gonna crimp it on here to our fuse tap. And then we can insert our fuse tap back into our fuse box. So now we've gone ahead and plugged that fuse right back into the slot that we had removed it from. Next, we're gonna hook up our ground wire. That's the black wire coming off of your harness here, right next to the red one. It's labeled "Ground" on there. For this one, we're just going to actually just put a ring terminal on it, and when we re-install our metal panel here, we're just gonna slide that ring terminal over the bolt. So I'm gonna give myself plenty of excess of wire here to where I could easily route that. So we're gonna just do right there and we're gonna cut off our excess, we'll strip back our wire now, and then we're gonna add on that ring terminal. Now the ring terminal does not come included with your kit, but you can get some here at etrailer. Next, we just need to plug everything in now cause the only connections left are the ground that we just made and that's gonna happen as we're reinstalling our panels. So we've got some electrical connectors now we need to cook up. We've got the main one coming off of the harness that we've been connecting here at the front. So we're gonna go ahead and just kinda separate these wires out here so we can keep things nice and neat. We'll then plug this into our module. This one's gonna plug into the color-coded black one that matches it. So that just plugs in there. Next we can take the wire that we had routed all the way from the back. We're gonna get to this one here. This one we're gonna tuck a lot of it, kinda underneath the carpet and the paneling here, but we need it to wrap around the back side here so it can plug into our panel I'm gonna put it on this side of the parking brake cable, just so that way all the wires are on this side of that parking brake cable. This is gonna plug into the other location on our module box. And then on your harness, you're gonna have another small connector on there. And this is over next to the white violet and brown wires. This is for your speaker, your audible speaker. So we can hear when there's an event occurring. So we're just gonna plug that in there. So these modules in this speaker, we look, we've got a pretty decent opening right here that our module could easily fit in. So we're just gonna be sticking this onto the backside of this panel, but for now, same with our speaker, we're just gonna be using the double-sided adhesive that comes included with it. But it will more than likely be easier to put these on after we get this panel up, because if we don't have it in the right spot, since this is pretty wide, we don't have a whole lot of leeway here. It would likely be easier right before you put this panel up, kinda line it up and stick it in place. So we're not gonna mess up our adhesive until we get to that point. But what else we can do before we put everything back together, everything is all plugged in. We've got everything that we need here except for our ground. So why don't we test it out before we go put everything together just to find out that we had accidentally missed something or one of our crimps wasn't a very good crimp, just any kinda little thing that can occur. So we're just gonna take one of those bolts, slide it onto that ring terminal real quick, connect that ground. And we're just gonna test it and see it is working here. So we've gone ahead and turned it on. We're gonna hit our left turn signal and we can hear that it's beeped and that we're getting activation cause we're inside of our shop sitting on the rack right now. So of course, it's gonna detect the rack next to us. If we turn our blinker off and then turn on our right turn signal, we can see over here that it is detecting something as well and that it is illuminated. So now that we've verified that everything's working properly, we we're able to operate both signals and get a feedback that it was detecting our lifts and stuff here in the shop. So now we're just gonna re-install everything in reverse order of how we removed it, zip tie up any loose wiring that we have. If you need some extra zip ties, you can get zip ties here at etrailer. We're gonna clean all that up. And then just don't forget that when you're reinstalling your panels, that you put that ground wire on your bolt before you put it back on. Right before I tighten them down, after getting the bolts started, this is a perfect place to put your module. So I just put the adhesive on our module. I peeled the other side off and then stuck it right here in this opening, right against the metal here. We're also gonna be putting our speaker. We're just gonna peel off the adhesive backing and stick that right onto the module. Now, as far as the grommet goes that we had pulled out on the ground, we're actually just gonna reinsert this one when we're putting stuff back together. I'm just gonna cut a slit in it like this. And you can if you point to like a small notch in it for your wire, you can do something like that as well, but really you just need to put a little slit in it. And then we can slide our wire through the slit and then reinsert our grommet, that way it'll pass down through below. You could also put a little bit of silicone on here, if you wanted to help seal it up. And now with everything all zip tied and cleaned up, we're ready to go hit the road. And that completes our installation of RVS's Blind Spot Monitoring System on our 2021 Chevrolet Colorado..
