If your 2015 Jeep Cherokee has the push button start switch that doesn't start the engine when the brake fuse is removed, the Roadmaster Brake-Lite Relay Kit # RM-88400 needs to be installed in the Normally Closed position. Here are the instructions for that proper installation:
Remove the green wire from the kit. If you are using a Roadmaster Even Brake supplemental braking system, set this wire aside to use later.
Locate the brake-light-switch wire in your towed car.
Remove the brake light fuse.
Cut the brake light wire a few inches away from the "cold" side of the brake light switch.
Attach the relay to the wiring for the RV braking monitor. The diagram above shows where the blue wire attaches the relay to either a Roadmaster Even Brake or BrakeMaster system. The green wire may be needed here.
Connect the black wire of the relay to the brake light wire near the brake light itself using the included blue butt connector.
Use a voltmeter to identify the wire in your aftermarket light harness that is conducting the tail light signal. Typically, this is a brown wire.
Using a 16 - 14 gauge butt connector (# DW05744-5; sold separately), attach a section of 14-gauge wire (# DW07550-1; sold separately) to the end of the red wire. Trim the new 14-gauge wire and connect it to your aftermarket wiring harness.
Start your engine and turn on your headlights. Test the tail light wire with a voltmeter. If your voltmeter doesn't register any voltage, move on to step 10. If 12V DC registers, you will need to install a single diode (# RM-790; sold separately).
Ground the white wire to your towed car's frame.
Secure the relay with the included wire ties.
I have attached a picture illustrating the installation for you. If this wasn't the problem let me know and I will help you troubleshoot further.
