Which Wire Goes Where on the Roadmaster Battery Charge Line Kit Part # RM-156-25

Published 02/22/2018

Question:

Re Item # RM-156-25, I purchased for my 2016 Jjeep Wrangler. I noticed during the installation that your installation video is at odds with the printed installation instructions. In the video, you instruct that the wire from the coach goes to the silver terminal. However, the printed instructions have that wire going to the copper terminal. Im assuming the printed instructions are correct as I think the purpose of the relay is to prevent power from the TOAD going back toward the coach. Just wanted to point out to you so video can be edited if needed.

The red wire that connects to the battery on your 2016 Jeep Wrangler Unlimited will need to be attached to the silver terminal labeled as "auxiliary" on the circuit breaker that comes with the Roadmaster Battery Charge Line Kit part # RM-156-25. The red wire that connects to the 6-pin trailer connector on the front of the vehicle which in turn runs to the motorhome's battery will need to be connected to the copper terminal labeled "Bat" on the included circuit breaker.

I have attached a quick wiring diagram I made for you to assist with the install. In reality, the circuit breaker only works one way so either method of installation will work through to be technically correct you will want to follow the instruction listed above.
