Does A 2024 Jeep Grand Cherokee 4xe Trailhawk Have A Plug-In Brake Controller Port

There currently aren't any listings showing the 4xe models having a tow package that includes a plug-in port for a brake controller so at this time the only available option would be a splice-in wire harness. For a 2024 Jeep Grand Cherokee 4xe I still recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR along with the Universal Wiring Harness # RED69FR because it has the smallest footprint on the market for more mounting versatility and a cleaner, factory look.

The wire harness will need to be ran in the following manner:

Black - 12v power with in-line fuse # 331-CBK30-EB
White - Ground
Blue - Brake output to trailer brake assemblies
Red - Cold side of the brake light switch

Since the brake light switch wire isn't useable on your Jeep you'll need to install the Roadmaster Stop Light Switch # RM77RR in order to simulate the signal for the red wire of the harness.
