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.

It's going to give us a four-pole flat, and it's going to provide us all the required lights to go down the road, such as our taillights, brake lights and turn signals. Now, this harness is a two-piece system. This section of our harness is going to attached to the back of our frame rail, while the other section is going to be attaching to the inside of our cab to the existing wiring. Now, let's go show you how we get it installed. To begin our installation, we're going to come to the rear of our vehicle and come real close to our spare tire on the inside of the frame on the driver's side. We're going to have two connectors here on the inside of our frame rail, and we're going to want to find the six-pin connector right here.

Trailer Wiring Harness Installation - 2017 Chevrolet Express Van

We're going to take a look at and also show you how to install the Tekonsha T1 Vehicle Wiring Harness with the four-pole flat trailer connector. Part number is 118392. Now when we're ready to use our wiring we're going to let that drape right over the rear edge of the door sill here. There's a rubber gasket all the way around the bottom edge of the door there meant to seal it up, and that's also going to offer protection for our wiring. We'll be able to just bundle this up inside of the van. I like to use the cover for my wiring to go around it, and keep it kind of bundled up pretty tidy there, and we'll tuck it out of the way. Now our installation's going to begin on the passenger side rear of the vehicle with our doors open.

Best 2016 Kia Soul Trailer Wiring Options

Today we're going to be taking a look at the best wiring options for your 2016 Kia Soul. Here we have the Tekonsha T-One vehicle wiring harness, and over here we have the CURT vehicle wiring harness. Now both of our kits are going to give us a four-pole flat to hook up to our trailer and give us all the required lights, such as our turn signals, stop lights, and clearance lights. Now both of them are going to stay on the outside of the vehicle until we're ready to use them. Let's take a closer look at some of the differences. Now one of the biggest differences, although it may be small, is the dust covers. Our CURT is going to have a removable and replaceable dust cover, whereas our Tekonsha is going to be built in. Now the way these are both going to be installed is we're going to have a t-connector that's going to go in between our taillights and our wiring from our vehicle. Now one benefit that CURT does have as far as installation goes is that the wires are going to be somewhat smaller at the connection points compared to the Tekonsha here, so it will be a little bit easier to get the wires in place behind our taillights. Now both our kits are going to have converter boxes so that we know that our trailer's going to get the right signal.
