Trailer Wiring Harnesses Troubleshooting

Today we are going to cover kind of a different subject. Basically, we are going to talk about getting your wiring installed and what is happening afterward. Okay, for instance, you went to the trouble to get your wiring installed, you plug it into your trailer, and nothing happens. There could be a lot of different things going on with it. First off, you need to figure out for sure whether it is on the towing vehicle side - the car or truck - or if it is something on the trailer. We will show you how to test the different types of wiring systems we have shown here. And that way you can tell for sure if it is your wiring harness or if it is your trailer.


How To Differentiate a Two Wire and Three Wire System

Today we are going to do the Frequently Asked Questions of what is the difference between a three wire system and a two wire system. It is actually very easy and very simple. All it is, is you take away two wires and the same thing applies to the four and five wire system. Starting off on the car side we are going to attach the wiring to, we are going to have five wires. Green is going to be right turn, red is going to be the brake signal, yellow is going to be left turn, brown is going to be your running lights, and the white is going to be ground. When you talk about the three wire system you are only talking about the right turn, the brake signal, and the left turn. You omit the brown wire and the white wire. That is our three. On the two wire system you are only dealing with the two combined signals, the brake signal and the turn signal on the same wire. We are only dealing with the left and right turn. 00:46


Trailer Wiring Harness Installation - 2006 Kia Sedona

Today were going to show you a popular upgrade. We have here a four pole flat that has been installed on a vehicle. The owner has a boat trailer now and it has a five wire flat. So were going to convert that four wire to a five wire flat. We will show you how to deal with part number 20036 which is the adapter itself, and the bracket which is part number 20046. Our first step we need to do is take off the four pole and then well uninstall the bracket and put in the new bracket. It may take some force, but you have to pull to get this out of here. We actually used a rubber mallet to tap it a little bit, now this bracket can come off which we have previously loosened up. Now well install our new bracket and it will go in the same spot as before. What were going to do next is get our four pole ready which we have cleaned out with WD-40 and then were going to put in some dielectric grease. Well put that inside here and then were going to attach our four pole from our adapter inside there.


How To Troubleshoot a Modulite Demo

Today we are going to troubleshoot a modulite that is not really working so we will check it out and show you what to look for. This will apply to all modulites and this will also apply to converter boxes as well. The only difference being that it does not have a power wire for a converter box. The first thing we want to do is put a tester on the 4-pole just to make sure. We will hook up our ground to our ground lead and then we will turn on the left turn signal which we have going, we have got nothing. You can turn on the other signals and see what we have got, nothing here. Try the running light circuit, nothing here either. 00:28


Testing and Troubleshooting a Modulite Vehicle Wiring Harness

All right today we are going to go over how to check over a modulite as shown right here which converts a 5 wire to a 4 wire system. We are going to go over the basics which are really simple. Basically we are just going to test input into the modulite and test the output of the modulite. That will tell us one of two things, we have no input going into the modulite, that means there is something wrong on the car side of the connector, there is nothing wrong with the modulite. If you have power going into it, but nothing coming out then you know chances are it is the modulite or there is a problem on the trailer itself. When testing you always want to test these modulites or converter boxes without the trailer hooked up first.


T-One Wiring Harness Explanation

Today we are going to show you a little bit of wiring. Basically kind of like wiring 101 and what to look for when your going to hardwire into the vehicle. What hardwire means is actually getting to the wire and splicing into them to make a connection. T1 connectors are different. They actually have a connection point and harness which you take apart and fit the T in the middle of that. Now on this vehicle we will show you the typical wiring schematics and a couple variants from that. The typical connection point is like where this wiring comes into the back of the tail light and there is always going to be a connection point, almost always. Older vehicles, it would have just ran straight, but with pretty much of your newer vehicles you are always going to have a snap connection like this. Basically a T1 connector simply would just go ahead and fit in between this harness.


Hot Lead Fuse Installation

Today on our 2005 Chevy Silverado, we are going to hook up the hot lead for the seven pull connecter at the back of the truck. To do this well simply remove the fuse box cover and the first position, on the first row is a blank fuse, we are going to remove it and install a 30 amp fuse. With that fuse installed, we can go ahead and replace the cover and were now hot at our seven pull connector. There you have it with the install of the hot lead fuse on our 2005 Chevy Silverado.

Trailer Wiring Harness Installation - 2016 Chevrolet Equinox

Today on this 2016 Chevrolet Equinox, we're going to review and install the T-One Vehicle Wiring Harness for the Factory Tow Package from Tekonsha, part number 118264. We just pull out what we need, put the floor panel back into place, and pull out our wire. Our door seal's thick enough when we shut it, it's not going to hurt the wire and we just run out whatever length we need out to your trailer at this point. Now, when you shut the gate, make sure that this is no where near the latch because you'll cut the wires and you'll be starting over. Just pull out a little bit right here. We can go ahead and shut our hatch and pull out what we need to go out to our trailer. As you can see, we have plenty to reach down to our hitch here and our trailer should have plenty of lead with it to match up to this. When we're finished towing for the day, we can go ahead and hide it back inside and be one less item hanging out below your vehicle. This is your 4-pole flat wire harness right here, with it's own built-in cover.


Trailer Wiring Harness Installation - 2016 Chevrolet Equinox

Today on this 2016 Chevrolet Equinox, we're going to review and install a Curt T-Conductor Vehicle Wiring Harness for the factory tow package, part number C56210. All right, now, when you're ready to use it, just open up the floor panel and pull out the wire harness. Put the panel back into place. It's not going to hurt anything. Then, run your wire harness to the outside. Just make sure you stay away from the latch, so when you close the hatch on it, it won't damage the wires. Then, after it's shut, you can pull out what you need to go to down to your trailer hitch and meet up with your trailer. You can see we have plenty of length to go down to your trailer hitch and meet up with your trailer. You got the wire harness itself.


Best 2017 Chevrolet Equinox Trailer Wiring Options

Today on our 2017 Chevrolet Equinox we're going to be taking a look at the best wiring options available. The two wiring options we're going to be taking a look at are the CURT T-Connedctor, and that's part number 56094. The second one is going to be the Tekonsha T-One Connector. That's part number 118494. Both are going to provide you with a four-pole flat connector for your trailer wiring at the rear of the vehicle. The main differences between the wiring harnesses are the Tekonsha here uses a power module. What this does is it connects directly to your battery, copies the signal to your trailer wiring, and prevents overloading your car's electrical system.
