Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 118796 Review

Today we're taking a look at a T1 vehicle wiring harness with a four-pull flat trailer connector. Now this is a vehicle specific harness. So to ensure that it is a fit for your vehicle, you can use the vehicle fit guide which is located at unit provides a four-way flat trailer connector at the back of your vehicle to power your trailer's signal lights. It is compatible with five pull, six pull, and seven pull adapters. Adapters are sold separately. And it comes with a dust cap for the four-way flat connector.

That way you can cover up the connection points when your plug is not being used.The black box is the included modulite. This ensures that your vehicle's wiring matches that of your trailers. The power module connects directly to the vehicle battery to avoid overloading your vehicle's electrical system. Now this is designed to connect quickly and easily. All you need to do is locate the connection points behind your taillights.

And then plug in your T-connectors.The one with the yellow wire goes to the driver's side of the vehicle. The one with the green and red wiring goes to the passenger side of your vehicle. These are custom fit so they will plug into the ports behind the vehicle's taillights. And then they snap and lock together for a nice, tight, secure fit. Once you have those plugged in, you'll need to make a ground connection.

That's your white wire with a ring terminal attached to it. You want to get that grounded to a suitable grounding location. And you can use the included screw to get that done.And then you'll need to mount the converter box to a safe, out-of-the-way location. You can do that with the included cable ties as well as the double sided adhesive foam tape.Then you'll need to run the hot lead to the vehicle battery. The hot lead is the short black wire coming out of the box.

This gets connected to one end of the bundle with one of the included butt connector. The other end of the bundle runs to the vehicle battery, gets another butt connector attached to it, and then connects to one-half of the fuse holder. So you'll cut that in half, splice back the wires a little bit, trim back the wiring to expose a bare wire. Place in the butt connector. The other end of the fuse holder gets a ring terminal attached to it and gets connected to the positive post of the vehicle battery.It does come with your 15-amp fuse. It goes directly in here and it's got the cap that goes over it to keep it safe and secure. Once you have that done, you can secure any excess or slack in your wiring with the included cable ties. And then once your install is complete, the four-way connector will be stowed beneath your vehicle near the trailer hitch. We do recommend using a mounting bracket to keep the connector secured and easily accessible. Mounting brackets are sold separately and available at We also recommend that you use a small amount of dielectric grease on all electrical connections like the plugs on the vehicle and the four-point connector itself to help prevent corrosion.When it comes to the maximum amperage for the stop and turn lights, we're looking at 5 amps per circuit. And for the taillights we're looking at 7.5 amps per circuit. That's going to do it for today's look at the T1 Vehicle Wiring Harness with a four-pull flat trailer connector.
