Does Tekonsha Make a Custom Wiring Harness for a 2024 Jeep Grand Cherokee

Question:

I am going to purchase the Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles - Proportional for my 2024 Jeep Grand Cherokee L and was wondering if it came with a wiring harness that connects to the Veh or do I have to buy separately? If I have to buy Separately then which one do I have to purchase? Thanks

Calvin, Tekonsha actually does not make a vehicle specific wiring harness for the Tekonsha Prodigy P3 # 90195 for your Grand Cherokee. The only harness that is offered is the universal wiring harness that comes with it.

Hey Calvin, were you able to get the Prodigy P3 wired up in your Grand Cherokee using the universal harness? Knowing how that setup worked could help others planning a similar install.
