Curt T-Connector Vehicle Wiring Harness Installation - 2017 Jeep Grand Cherokee

Today on our 2017 Jeep Grand Cherokee, we'll be having a look at and installing the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package with a 7-Way and 4-Pole Flat Connector, part number C55774. We have our 7-way adapter here. This will allow us to tow a multitude of different trailers, such as ones that have electric brakes, provided we have a brake controller installed inside of our Jeep. Over to our side, we have a separate 4-pole flat, which is what most standard small trailers use to control their lighting functions, including most rental trailers. What's nice about having this to the side of your 7-way, is you don't need to have an adapter in order just to tow a small trailer; you have the option for both right there, no adapters required, one less thing to worry about losing. What I really like about our Curt wiring harness that we have here compared to some of the options from some of the competitors out there, is that it's a complete package. We have the 7-way, we have our 4-way, we have a bracket to mount it to our vehicle, and it goes right into the vehicle's existing tow package wiring, no modifications to the vehicle required at all. Now, one thing I would like to point out, once you install this wiring, it probably won't work in most cases. You'll have to go to your local Jeep dealership and have the computer re-flashed inside the vehicle in order to enable the factory tow package.

Today on our 2017 Jeep Grand Cherokee, we'll be having a look at and installing the Tekonsha Multi-Tow 7 Way & 4 Pole Trailer Connector.

It gives us both, no adapters needed, they're both right there. It comes with the brackets you need to mount it, has just the right length wiring harness to plug into your factory tow package wiring, and it provides us a nice clean installation. In most instances, we're going to have to make a trip to our local Jeep dealership in order to have our computer flashed on our vehicle so our tow package wiring is actually enabled. All the physical connections are already there in most instances but the software needs to be turned on in order for them to work. Now once it has been enabled this will give you on your 4 pole flat connector over here your tail lights, your turn signals, and your brake lights for your trailer.
