Testing and Troubleshooting a Modulite Vehicle Wiring Harness- Video
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. more

Trailer Wiring Harnesses Troubleshooting- Video
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. more

5 Wire vs 4 Wire System Demonstration- Video
To tell if your vehicle has a 4 or 5 wire system what you want to do is have a friend go ahead and step on the brakes. And note which lights come on. Now what you want to do then is go ahead and turn on the turn signal while holding the brake down and turn on the right turn signal. As you an see you have your brake lights on and you see the amber turn signal going on to let you know you have a 5 wire system. Now on this vehicle here we have a 4 wire system. The way to double check that is go ahead and turn on one of the turn signals like the right one here. Note which bulb is burning and which filament on the inside and turn that off. Then go ahead and hit your brakes. And you notice here, it is one in the same. So that means your turn signal and your brake lights are one in the same and you just use a regular 4 wire system you do not need a converter. more

T-One Wiring Harness Explanation- Video
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. more
