Question:

the charge line for the motorhome went to the #4 tab auxinch on the hitch connector but the video for the 2015 6 pin jeep went to the center pin. I have a 7 pin on motorhome and on jeep. Which pins do the charge lines go on for both? Thank you,

Expert Reply:

The charge lines connect to the 12V pin on both the 7-way of your motorhome (1 o'clock position) and the 6-way (center pin). The wiring pigtail will ensure the connection between these pins so your motorhome will provide a maintenance charge to your towed vehicle battery.

You will want both the Roadmaster Battery Charge Line Kit for Motorhomes # RM-156-75 and the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25. I've attached an installation video of each kit to assist.

If you have a 7-way on the front of the Jeep then the charge line will connect to the 1 o'clock position there as well.
