I am towing a MDC XT12HR OGE trailer with my Overtrail. For the Renogy DC to DC charger in the camper, It needs an ignition signal from the towing vehicle (when it has a smart alternator) to tell the charger to accept current from the vehicle to charge the camper's lithium battery. I have installed a separate charge cable from the GX's battery that connects to a lead on the trailer (via an Anderson Plug) to carry the charge current.
The trailer owner's manual says:
1. Anderson plug wiring must be correctly installed with appropriate fusing. (I have had this done as mentioned above)
2. Ignition trigger (from the trailer connector’s Pin 4) must be activated to enable alternator charging. For vehicles with smart alternators, the ignition trigger is mandatory for proper charging recognition.
Here's the diagram for the 7-pin connector from the camper's owner's manual.
Thanks!
