Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 56043 Review

Today we're going to review part number 56043, this is the Curt key connector vehicle wiring harness with the 4-way flat trailer connector. This wiring harness is a custom fit part, it is designed to fit the 2003 to 2007 Cadillac CTS vehicles. With a custom fit part, I always recommend to go to our website, use our fit guide, put in your year and model vehicle and it will tell you if this will work for your application. Now this harness provides this 4-way flat trailer connector in the back of your vehicle to power your trailer signal light. Connects very quickly and easily, just locate your connection point which is in your rear cargo area, plug in the T-connector right here, ground your white wire, run your power wire to your vehicles battery and you'll be all ready to go. That does include this tail converter, this black box right here to ensure your vehicles wiring match the head of your trailer. This is a power module converter, that means it connects directly to the battery, using this power wire, the reason they do that is to avoid overloading your vehicle's electrical system. The converter box right here, the black box is constructed using SMT technology which is surface mount technology. This will give you consistent, reliable performance, helps maximize your trailer light, yield and intensity while producing minimal heat and ensures superior operation in any rough road conditions. This part also comes with a nice dust cap for your 4-way, so what you can do is just attach this to your 4-way plug and you can leave it on there if you like, but what's nice is when you're not plugged into the trailer you can just put your cap over the terminals, protect it from any damage or the elements. A few specs on this harness, next ampridge 00:01:34 for the stop and turn light circuit is 3 amps per circuit.

For the tail light circuit is 6 amps total. Now this part includes everything shown here on the table that I've laid out, even has a nice set of detailed instructions to tell you how to install it but also gives you pictures to show you where the connection points are, helps out quite a bit. Basically what you'll do to install this, just go to the back of the vehicle and as I mentioned in the rear cargo area, you'll locate a connection point which it will show you in the instructions where it's located and you'll just unplug it and plug this in line to it. Once that's all plugged in the white wire right here with the eye lid on it need to connect that to a good clean ground. If there's one nearby you can use it. Need to make one, there's a grounding screw, that you can drill a hole and make a ground and then you have your power wire right here.

This has to run to your vehicles positive post of their battery so that has to run to the front of the vehicle, so they give you this extra length of wire. Take one of your butt connectors, put it on your power wire coming out of the converter and connect it to one end of your length of wire, run that wire all the way up toward the front of the vehicle, using these cable ties to take up any slack in that wiring. Once you get to the front with the other end, you don't want to connect this to the battery yet, you want to run it through this in line fuse holder. So take your other butt connector put it on there and connect it to one side of the in line fuse holder, just like that. Once that's all connected, you have your other side of the fuse holder, that's what will connect to the positive post of your battery, they includes this eye lid connect that you put on there, connect it to the positive post. Last thing you need to do is take your included 10am fuse, put it in the fuse holder just like that, put the cap on and you'll be all ready to go. Now one other thing I do want to mention to is this converter box, this black box here, it does need to be attached to a nice flat surface so it doesn't bounce around, so they do include some double sided tape to help with you that and some extra cable ties that you can also use to secure if you like. That should do it for the review on part number 56043, the Curt T-connector vehicle wiring harness with the 4-way flat trailer connector.
