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.

In order to do that, you can take it and simply bundle it up in here, right down in there so it's out of your way and you've got full use of your cargo area without needing to worry about damaging that wiring. When you're ready to use it, you just pull it back out and then you can close the trunk. You want to make sure to avoid the latch area so that it doesn't pinch the wiring.

When we're ready to hitch up out trailer, we can take our floor flat connector that's going to be stored away in this pocket on the passenger side of our vehicle. We'll lay it across the back of the vehicle, across the weather stripping. You just want to make sure you keep away from the center here so that we don't pinch it into the latch and then just close our hatch down on top of it and plug it into our trailer and then when we're done, we simply open it back up. We'll take our wire and we'll just kind of bunch it up and we can take our weather tight tap and use it to capture our wiring and keep it nicely tucked away. Now it's a nice little package we can put down inside the back here. Reinstall our cover and it's all completely hidden away. That's what our kit's going to consist of.

Trailer Wiring Harness Installation - 2008 Saturn Sky
Today on this 2008 Saturn Sky, we're going to review and install the draw type 4 pull hard wire kit with circuit tester, part number 18252. A couple notes on when you're not using it, of course, it's going to stay right here and we can go ahead and shut the trunk hatch on it. It should present no problems. Then when we need to use it, we'll simply pull it out, take out our slack, just run it out the back here. There's enough gap right here it won't hurt the wires when you close the hatch. There's plenty of space in here, I can move the wire so nothing will get pinched and plus we have enough to go down to our trailer hitch. Keeping it somewhat inside the vehicle will make the contacts on the 4 pull last a lot longer than sitting outside all the time. This is the parts that you get.
Curt Custom Fit Vehicle Wiring C56317 Review
Today, we're going to take a look at the Curt T-connector Vehicle Wiring Harness with the Four-way Flat Trailer Connector. Now this is a custom fit part. It is designed to fit the Toyota Prius, starting in 2016. Now what I would recommend on any custom part is you go to our website, use our fit guide, putting in your model vehicle, and it will show if it will work for your application. Now this harness will provide this four-way flat trailer connector at the back of your vehicle to power your trailer's signal lights. This is compatible with five pole, six pole, seven pole adapters that we do sell separately. This harness does connect very quickly and easily.
Today on our 2017 Subaru Forester we're going to be taking a look at and installing the tow ready T1 vehicle wiring harness with 4-pole flat trailer connector, part number 118467. Here's what this wiring is going to look like once it's installed on the vehicle. As you can see we've got access to it from underneath the trunk here. When it's not in use it's easy to tuck it away inside the trunk so that way it maintains a nice, clean look when not in use, but it's also very easy to access whenever you do need it. Now with this wiring one of the nice things is that with the way it's set up, it plugs directly into the vehicle's existing wiring system instead of having to put T connectors behind the tail lights and then run it down. This way it's a lot simpler and a lot more straightforward.
Trailer Wiring Harness Installation - 2016 Hyundai Santa Fe
Today on our 2016 Hyundai Santa Fe, we're going to be taking a look at and installing the tow ready T-1 vehicle wiring harness for the factory tow package with a 4 pole flat trailer connector, part number 118-269. Here's what this wiring is going to look like once it's installed on the vehicle. As you can see, we've got good access to it here on the bracket that's already provided on the hitch. We just use a 4 volt bracket here to mount it and so it's nice and accessible and easy to use whenever we need it and it's got that nice dust cover to cover it to help keep water and the elements out, to prevent corrosion, and make sure that you've always got a good connection there. What's nice about this wiring harness is that it's very easy to use. It simply plugs in to the factory wiring harness connectors and then you just need to mount up the rest and tuck away the wire and you're ready to use it. This wiring harness, being that it's easy to use, you're not really going to need to worry about doing any type of maintenance or anything and with having that module box and in like fuse, it's going to help your vehicle's electrical system from any back feed in case there's a short in the trailer.
