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

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 - 2014 Ford Focus
Today on our 2014 Ford Focus Five Door we're going to be installing the Tow Ready T1 Vehicle Wiring Harness, part number 118549. We're going to begin by raising the rear hatch of the vehicle. Now that we have our rear hatch open go ahead and set this trunk cover aside for now. Go ahead and set the spare tire out as well. The reason why I took all that out is to gain access to this grommet that we'll be using in a little bit. Now that we have the trunk area cleared out next we're going to need to remove this panel right here to gain access to the nuts that are behind the taillight assembly. Simply push in and pull outward and set it aside. Now with our panel removed let's go ahead and point out the two plastic nuts that we'll need to remove.

We'll go ahead and begin our installation by raising the rear hatch of the vehicle. Next we'll need to lift the rear cover here up and out of the way. Go ahead and just lift it up and then just clips out. Go ahead and set that out of the way for now. We'll then need to remove this whole rear threshold piece.
Fifth Wheel and Gooseneck Wiring Harness Installation - 2001 GMC Sierra
Today on our 2001 GMC Sierra, we'll be installing the Pollack 5th Wheel and Gooseneck Trailer Connector, part number PK11893-11932. Now to begin our install, we'll first go ahead and find a location to mount the new 7-pole connector and drill out our holes. In our pickup bed on the driver's side just behind the rear wheel well is a good location. Using a 2-inch hole saw bit, we'll go ahead and drill out our hole. Now in order to get our wiring harness fed from underneath and up through our hole, we'll need to remove the two fasteners that secure the mudguard here behind the wheel well. There's one just on the inside of the wheel well lip and one underneath the tail light area. Once we have the fasteners out, we can go ahead and pull the guard down. Now that we have the wire fed into position, we'll move back to the pickup bed where we'll install the wires into the back of the connector. Now when installing our wires, each connector is faintly marked with a number.

We're going to remove the blank that holds the wire harness in place. Now, I already have it loosened up. You can pull it out. This is our new part here.
Trailer Wiring Harness Installation - 2000 Mercury Grand Marquis
Today on our 2000 Mercury Grand Marquis we'll be installing the Tow Ready Circuit Protected Module Light with Four-Pole Harness, part number 119179KIT. To begin our install we'll first need to hook up our new module light and wiring harness. To do that we'll need to locate the manufacturer's wiring that runs to the rear taillights. To do this we'll go ahead and remove the four push pin fasteners securing the rear threshold. Next we'll go ahead and remove the rear threshold and sit it aside. Now by the removing the plastic hold down fastener for the carpeting we can peel back the carpeting along the threshold and behind the driver's side taillight assembly. Here we'll locate the wiring that runs to both taillights. To access the wiring we're going to go ahead and use our utility knife to cut back the electrical tape and cover and remove it so that we can use our test light to probe each wire to locate the running light, turn signal and brake circuits. Now for this application it's a combined setup so the turn signals will also act as the brake light signals.
Trailer Wiring Harness Installation - 2012 Volkswagen Jetta SportWagen
Today on our 2012 Volkswagen Jetta Sport Wagon we'll be installing the Tow Ready Custom Fit Vehicle Wiring Harness with Four-Pole Connector, part number 119179KIT. To begin our install we'll first need to remove the spare tire cover and lower storage cover. Then we're going to remove the cover panel behind the passenger side taillight assembly. Using a flat blade screwdriver we'll get in behind the cut out panel and go ahead and sat it aside. Then on the driver's side we'll go ahead and fold down the access compartment by unlatching the two twist knobs and then pulling back on the cut out of the carpeting to expose the wiring behind the driver's side taillight assembly. Now that we've exposed the wiring behind both taillight assemblies we'll need to remove the rear threshold. To do this we'll remove the two fasteners that secure it. Once we unscrew them we'll set them aside we can gently pull up on the rear threshold releasing the fasteners underneath. Now with that done we'll need to identify the running, turn signal and brake lights.
