What Circuit of the Roadmaster RM-155 Does the Brown Wire Run to

Question:

After wiring my jeep. I tested the lights, and both turn singles and the brake lights work, but the tail lights dont work. Ive checked the wiring connections, 4 wires. White is ground, which I grounded at my right tail light, the yellow wire is the left turn, the green wire is the right turn and the brown wire is for both the brake and tail lights. I have 4 wires coming from my RV which worked fine on my 2007 Jeep wrangler.

The issue is the way you wired up the brown wire. This needs to run to the running light circuit of your vehicle. This is the circuit that activates the dimmer illumination of the trailer lights you have on your vehicle. It would not run to both the brake and turn signal circuit like you mentioned.

I attached a link to an install video for the # RM-155 being installed on a similar Liberty as yours.
