Where does the Tekonsha Wiring Harness Plug into on the 2019 Chrysler Pacifica Limited Van


Where does 118712 plug in on my 2019 Chrysler Pacifica Limited van ?


Expert Reply:

The Tekonsha wiring harness part # 118712 plugs into the vehicle's wiring harness behind the driver's side and passenger-side tail lights. The tail lights need to be temporarily removed to find the wiring harness to plug into. There are two screws on the side of the taillights closest to the cargo area. There is an electrical connector behind the tail lights that needs to be disconnected by pressing down on the locking tab. I have attached a photo of what this connector looks like. The factory wiring connectors are on both the drivers side and passenger side tail light assemblies. Once you plug the Tekonsha harness into the connectors on each side, you can reinstall the taillights by reinstalling both screws.

Since the Tekonsha wiring harness does have a ModuLite box included, the black power wire needs to be connected to the positive side of the vehicle's battery. The ModuLite prevents overloading the Pacifica's electrical system because it draws power from the battery instead of the vehicle's wiring. I have attached a help article about running the black power wire from the box to the battery and an installation video of the Tekonsha wiring harness part # 118712 on a 2018 Chrysler Pacifica.
