Installing Battery Charge Wire Kit For Motorhome and Towed Vehicle Connection

Question:

I bought the RM 156-25 for my 2016 Chev Equinox because of battery drain. Th video does not tell me which pin on my plug this is supposed to go to. Some one at Etrailer told ne to put it on the pin at 11 oclock when looking at the front of the plug. There is already a wire going there and I think it is for one of the turn signals from the HM56108 I have installed. I was also told if the motor home does not have a charge line installed I would have to put the RM 156-75 kit on the motor home. I can not do this because I deliver new RVs and this is impossible. What can I do to keep my towed vehicle battery charged??????

The Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 should be installed to the center port of the 6-way trailer connection. If you have a different connection, let me know as most charge kits have this 6 wire connector on the towed vehicle and a 7-way on the motorhome.

If you don't already have the charge line for your motorhome, then you will want to use the Roadmaster Battery Charge Line Kit for Motor Homes # RM-156-75 which will have you connect the new wire to the 1 o'clock pin of your 7-way when facing the connector which is the 11 o'clock position on the back of the connector. I've attached a photo with the labeled functions to assist as well as a video.

This connection will give you a maintenance charge between your motorhome and Equinox.
