Good Quality - Works - Installation is Very Involved.
June 24, 2019
The installation instructions cover all of the steps but are not detailed. You have to remove the tail lights, rear bumper, and all of the trim panels on the passenger side from the rear to the front passenger footwell. Wiring is routed from the front bumper through the firewall and to the rear. Not particularly complicated, just several steps to figure out. Two issues to resolve: the wiring harness has to be installed to the interface connector (where the umbilical cord from the tow vehicle plugs into the wiring at the front bumper). The pins that insert into the connector are tiny, and several broke off. Replace the Mopar proprietary connector with a generic six-pin waterproof connector. Requires some soldering but a much better solution. Also the 7-way connector at the tow vehicle is wired per the standard wire color coding, and the harness has the same color wires, but do not perform the standard function. Easiest solution was to determine by trial and error what color does what, and re-wire the 7-way plug accordingly.
ProsPlug and Play - when the jeep umbilical is plugged into the tow vehicle the 12-volt aux activates relays that switch all tail light functions to the tow vehicle control. No risk of feedback from one vehicle to the other. Provides a wire for brake signal from the tow vehicle, to be used if needed for a braking system in the towed vehicle. Mopar part - warranty on the harness and the jeep remain effective.
ConsLengthy installation. Plan on at least a day of work. Proprietary connector - pins broke during install - could not use. Pre-wired connectors not wired correctly.
