Review of Curt Custom Fit Vehicle Wiring C55381


Today we're going to be taking a look at the Curt T-Connector Vehicle Wiring Harness for our factory tool package. This is going to provide you a 4-pole flat trailer connector. This product is going to fit in multiple vehicles, so please use the Vehicle Fit Guide, located at etrailer.com, to see if this is a fit for your particular vehicle. It's going to provide a 4-way flat trailer connector at the back of your vehicle, that's going to power your trailer signal lights. This is designed for use with the factory tool package that already has a 7-way connector. When installing this, this does retain the 7-way connector functionality, and it's going to come with a dust cap for the 4-way flat connector, that way you can cover up the connection points when your pole is not being used. A benefit of this system is how easily it installs, you don't have to worry about cutting or splicing any wires.

Just locate the connection points behind the rear bumper, take these large connectors, and plug them into the connectors on the vehicle. They're going to match up perfectly, they're going to snap lock together for a nice, tight, secure fit. Then you can simply just use the included zip ties, to secure the excess wires that you may have. Once your install is complete, the 4-way connector is going to be stowed beneath your vehicle and the other trailer hitch, you can loop it around the safety chain loop, or you can purchase a mounting bracket. Mounting brackets are sold separately, but they are recommended to help keep the connectors secure. It is also recommended that you use a small amount of dielectric grease on all your electrical connections, like the plugs on the vehicle, and the 4-pole connector itself, and that's going to help prevent corrosion.

If you need some of that, you can find it right here at etrailer.com, that's going to be sold separately. That's going to do it for our look at the Curt T-Connector Vehicle Wiring Harness for factory tool packages, which is going to provide your 4-pole flat trailer connector.

Does a curt 55381 fit on a 2005 Jeep Grand Cherokee? I bought one and I can’t figure out how it goes?

It is if you have the factory tow package. If you don't have the factory tow package then you need part # C55451 instead. If you have the factory tow package then you should have some connectors under the bumper on the driver side. These will match up with the Curt wiring kit that you currently have.
