Which Pins to Use for Charge Wire of # RM-156-25 When Attaching to Trailer Connector

Question:

I have installed the RM-156-25 towed vehicle charge line kit on my 2016 Jeep Wrangler Sport. Instructions stated connect the 12 volt power line to the center pin of the 6 pin plug. Now I have ordered the RM-156-75 motorhome charge line kit. I see that the instructions for this kit calls for the 12 volt power line to be connected to the number 4 pin of the 7 pin motorhome plug. My question is that since the center pin on the 6 connector plug and the number 4 pin on the 7 connector plug do not align is this the correct connections for these two kits to work together supplying 12 volts to the towed vehicle battery? Thank you for your reply.

The center pin of a 6-way is typically the 12 volt accessory circuit which is commonly used for charging batteries. The same 12 volt pin on a 7-way is the one in the 1:00 position.

Between the two connectors styles those are the correct pins to use.
