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.
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.
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
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 - 2015 Lexus RX 350
Today on our 2013 Lexus RX350, we'll be installing the Curt Vehicle Wiring Harness with 4-pull flat connector for factory tow package equipped vehicles, part number 56083. Now to begin our install, we'll first go ahead and remove some of the fasteners of the underbody panel here back by the hitch just below the rear bumper. Starting here we're going to go ahead and remove the screw fasteners along the back edge and on push pin fastener. To remove the push pin fastener, we'll go ahead and pry out on the center to release it and then remove the fastener. Now we'll just gently pull down on the panel exposing the back edge and the manufacturer's tow port. The tow port has a weather tight connector covering the end and we'll need to remove it. To do that you'll press on the locking tab of the connector, pull down and it'll release the end and we can set it aside as it will not be re-installed. As you can see this will expose the manufacturer's 4-pin connector.
Trailer Wiring Harness Installation - 2005 Ford F-350
Today, on our 2005 Ford F350 Super Duty Crew Cab, we're going to be installing the Bargman 5th-wheel and gooseneck 90-degree wiring harness with a 7 pole and a 9 foot long lead. Part number 51-97-410. This vehicle does already have a 7 way gooseneck and 5th-wheel wiring but we're going to be replacing it with a new Bargman 7-way 5th-wheel gooseneck wiring. First remove the existing wiring that's already in place so that we can install our new wiring harness. I moved up here to the bed of the truck and as you can see there is already an existing 7-way plug in the bed that's part of the wiring we just undid underneath. This right here is what we'll be removing. Remove a couple screws that hold it in place. The new Bargman gooseneck 5th wheel wiring will actually tie in with the factory wiring and will allow you to use the 7-way down at the bumper as well as the new 7-way plug that will be mounted up here in the bed.

Today on our 2014 Cadillac SRX we're going to be installing the Curt T-Connector Vehicle Wiring Harness with a 4-Pole Trailer Flat Connector, part number 56096. We're going to begin here on the lower rear fascia of the vehicle. We're going to need to remove this center section. To do that, we'll need to remove the Phillips head screw here as well as over there. Once your screws are both removed just simply lean the panel downward. There's five little tabs at the top that you'll need to get to release. We're going to go up here underneath the bumper structure itself.
Trailer Wiring Harness Installation - 2012 Chevrolet Traverse
Today on our 2012 Chevy Traverse, we'll be installing the Curt T Connector Wiring Kit, part number C56027. To begin with, we'll need to raise the rear hatch of the vehicle. Then we're going to go ahead an remove both of the taillight assemblies. To do this, there are 2 small plastic tabs that we'll need to remove from each side. They will not be completely removed, as they are connected by a small plastic tether, which you'll need to lift them out of the way so you can remove the one screw that is in each hole. Once you have the screws removed and you pull the light assembly off the vehicle, you need to remove the wiring harness from the back of the light. To do this, you'll squeeze the tab and pull the wiring harness free.
Today on our 2014 Cadillac SRX, we're going to be installing the Tow Ready T1 Vehicle Wiring Harness with a 4-pole flat trailer connector with vehicles with a factory tow package, part number 118259. Now we're going to go ahead and start here at the center of the vehicle on this lower fascia piece at the rear bumper. We're going to need to remove this screw here as well as this screw here. Both of these are just a Phillips-head, so we'll just be using a Phillips-head screwdriver. Once the screws are out, lean the center door section down, and it'll just pop out of the 5 tabs that are at the top. Now if you look up here underneath the rear bumper right here on the back side, this right here is the plug that we're looking for. Now to make things a little bit easier, we're going to go ahead and remove it from the plastic tab securing it to the bumper.
