How to Install the Tekonsha T-One Vehicle Wiring Harness on a 2017 Acura RDX


Speaker 1: Today on this 2017 Acura RDX we will be having a look at, and installing, the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part number 118569. Here's what our wiring looks like installed.This wiring harness gives us the basic lighting functions that are required by law in order for us to safely tow a trailer. This black wire here, with the white stripe, is our necessary ground connection between our RDX and our trailer. The wire with the brown stripe, that is our taillight and running light circuit, and on that wire we have a total power output of 7.5 Amps, which is more than adequate to run several incandescent lights, or basically as many LED lights as we want, because they do draw less power.On our black wire with the yellow stripe, that is our left turn signal and left brake light. On that circuit we have a total power output of 4.2 Amps. Tekonsha does recommend a maximum of two lights on that side, so if you have incandescent lights, limit them to two.

You can run a little bit more with LED lights because of less power draw. The wire with the green stripes, that is our right turn signal and right brake light, and again, on that circuit we have 4.2 Amps of power output.Built into our connector, we have a nice dust cover here to help better protect it from the elements if you do decide to mount this outside. I recommend using some dielectric grease on the inside, which we have available on our website, to help prevent any corrosion that could occur. When this wiring harness is not in use, we can store it nice and neat on the inside of our vehicle, out of the way, so we don't have to worry about any of our cargo damaging it as we're loading and unloading our hatch. We can store it inside this compartment over here, slide our cover back into place, and it's like our wiring harness is not even there.Now that we've gone over some features, we'll show you how to get it installed.

To begin our install, we'll open up our rear hatch. Now, on the driver side of our hatch we'll find a cover for our compartment; take a flat head screwdriver, pop it open. Now, just behind this area right here, we'll show you where the factory tow package connector is. So this blue connector, that is our factory tow package connector. Here on our tow package harness here, this blue connector will plug in to the blue connector inside.

It only goes in one way, so just line it up and push in till it clicks into place. Pull back to make sure it's secure. And now we'll show you what it looks like connected.Okay, this white wire here, with the ring terminal on it, that is our ground wire. We can attach this to our vehicle's body with a self tapping screw, or we can remove one of these 10 mm bolts next to this module box here, and secure it in place to that bolt, that way we don't have to drill any holes in our vehicle. Okay, with the bolt removed, we'll place it on the ring terminal, and reinstall the bolt.

This will give us a nice solid ground for our wiring harness to work properly.Now we can take our module box and plug it into our wiring harness. inaudible 00:03:43 only goes in one way, and we'll lock it into place. Now we'll take a zip tie, go through this hole here, and we will secure our module box into place with that zip tie. We'll tuck our wiring inside. For the 4-pole flat wire we have a couple different options here. We can store it inside this compartment when it's not in use, and for video purposes that's what we're gonna be doing here today. We can also route it underneath the carpet and the foam panels here, to where the spare tire would reside if we had one. Or if you wanted to have it outside the vehicle, there's a grommet underneath here that you can knock a hole in and run the wiring outside the vehicle, and permanently attach it out there with some brackets.And now we find ourselves underneath the hood. This is our fuse box right here. We'll open it up, we have two tabs, one here and one over here; press in on those, open it up. And right in the middle, right here in this unoccupied spot close to our air box, we'll install our provided 20 Amp fuse. This provides the power to our factory tow package connector. Now we will close our fuse box.Okay, now we're gonna test our wiring using a 4-pole flat trailer tester, which we have available on our website as part number I26. The reason we're using this over just hooking up to our trailer, is this will test the vehicle properly. If we had a problem with the trailer we wouldn't be able to tell if the vehicle's working right. With our headlights on, you can see our taillight and running light functions working. Left turn signal's working as well. Right turn signal's working too. Our brake lights are working. And we'll double check our turn signals while our foot's on the break. Everything's working properly.And that completes our look at, and installation of, the Tekonsha T-One Vehicle Wiring Harness, with 4-Pole Flat Trailer Connector, part number 118569, on this 2017 Acura RDX.
