T-One Trailer 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.

Usually there is a little tab right here that you push down, somewhere on the assembly, and you pull it apart. Then your T connector would actually fit in between here and then your wiring would come off from there. That is essentially how a T connector works. Most of the time you will have just one connection that you make. But occasionally on a T connecter you will have to go from two different places. Basically you will have to tap in behind the driver side tail light and then run a wire to the other side on the T connector to the passenger side also. A lot of T connectors are like that. It is just how the wiring is made because the wiring on vehicles predominantly come in two different varieties. In this application here, the wiring harness actually comes down the driver side and comes across here to the tail light on the driver side, tees off, goes into the drivers light, and then goes on over to the passenger side tail light. Now also, that split right here, instead of it being right here to T off, that could be in the other varieties, goes up further back into your vehicle. A lot of mini vans and SUVs are like this. The harness will have just one going down each side of the vehicle. At that rate you are still going to have to go from one side to the other to make your connection points. Like this particular instance we could tap everything from this side of the vehicle to the harness right here. It is kind of more of the exception then the norm. A lot or times it might not be practical to go right here if you know where the harness is. It might just be easier to make your connections behind the tail light, run it underneath the plastic, across and back to the other side and just keep everything in the trunk area. So you do not have to take apart all of this stuff.
