Review of Curt Custom Fit Vehicle Wiring C56189

Today we're going to review part number C56189. This is the curt T-connector vehicle wiring harness with the 4-pull flat trailer connector. This is a custom fit part number. It is designed to fit the Mitsobichi Hotlander, starting in 2014. This will provide a 4-way flat trailer connector at the back of your vehicle, to power your tailer signal lights. Basically, to install this, it connects pretty quickly and easily.

It uses the T-connectors, so there's no cutting or splicing of the wires. You just plug them in. You do have to run a hot lead to the battery to supply the power. Now this part does include this tail light converter, and what that allows it to do is, just ensure that your vehicle's wiring will match that of your trailer. It is a power module. That's why you use the 12-volt hot wire connected to your battery, because you want to avoid overloading your vehicle's electrical system; so you run the power straight through the converter to power your tail lights on the trailer.

Now this converter is constructed using a surface mount technology, which will give you consistent rival performance. It does maximize the trailer light yield and intensity, while producing minimal heat, and it gives you superior operation in any rough road conditions. Basically, when you go to install this, it does come with a set of instructions with some nice pictures; very helpful. What you'll want to do, to start off, you have to go to the back of the vehicle, and in the back of the vehicle, you have to access the rear tail lights, both driver's and passenger's side. What you'll do is, find the T-connector that has the yellow wire in it. That would signify that that's for the driver's side.

What you'll want to do is behind your tail lights, unplug the wiring harness to the tail lights. Plug this into the tail lights. Plug the wiring harness in, so this is T'd into there. Then what you also want to do is, there's a white wire coming out of the converter that has a ilit on it, an I connector. You want to make sure this gets grounded to a nice, clean ground, if there's one already on the vehicle.

If not, you could drill a hole, and use the self-tapping screw, to get a good, clean ground. Then what you'll want to do is run this green wire T-connector over to the passenger's side tail light, and the same way like you did on the driver's side, is you'll disconnect the wiring harness from the back of the tail light. Plug it into here, plug the wiring harness back in, so this would be T'd into, on the passenger side. Now the remaining thing you'll need to do is, you'll take this black power wire that comes out of the converter. This needs to be run to the front of the vehicle, and hooked to the positive post of the 12-volt battery; so they do give you this length of wire and these but connectors. What you'll want to do is take a but connector, and install it onto that power wire coming out of the converter, and then take one end of this wire and connect it to there. Then run this wire all the way to the front of the vehicle. When you get to the front, take this open-end of this wire that you ran to the front, put the other but connector on. Before you connect this to the battery, you'll want to connect it to this in-line fuse holder. You just put one end of the in-line fuse holder into there, connect them all together, and you'll have this open end over here. You'll take this round ilit that's included, put it on the other end, and then this is what will be connected to the positive battery post on your battery. Then what you'll want to do is open up this in-line fuse holder, take this included 10-amp fuse, go ahead and insert it into the holder, itself. Then once you get it all inserted, you just put your dust cap over that to protect the fuse holder. It does also give you some extra zip ties, so when you run this length of wire from the back of your vehicle to the front, you'll be able to zip tie it, keep it from hanging low, or hitting any hot areas. Also gives you this double-faced tape. What you'll want to do is, I forgot to mention that you'll take this converter, and then use this double-faced tape, and attach it to a secure location, on usually, the driver's side of the vehicle; because it will be closer to the T-connector, on the driver's side. Just use this to put this in a nice location, out of the way. Then, once you have it all . It does also include this dust cap. Basically, this is your 4-way, that would run out the back of your vehicle, for your trailer to plug into. You can use this dust cap, when you're not using the 4-way. Just leave the dust cap on there. Let's put it on, the other way. There you go. Then you can just put that onto your 4-way, to protect it, when you're not using it, just like that. That should do it for the review on part number C56189, the Curt T-connector vehicle wiring harness with the 4-pull flat trailer connector. .
