Hello Erik.
I do not have the wiring schematics on the vehicles. I would reach out to Jeep to find out what color wire it is, or you can push down the brake pedal and check the wires with something like a Hook Probe Circuit Tester # PTW2993 to see which wire is getting 12 volts when the brake pedal is down.

Hey Erik, were you able to track down the correct brake signal wire on your Grand Cherokee after checking with Jeep or using the circuit tester? Knowing what worked could help others trying to wire a brake controller on the same vehicle.
