Hey David, the pin in the 1:00 pin position of the 7-way part # HM40975 is the 12 volt accessory circuit that you would need to connect the battery to. 1:00 as you are facing the open connector from the front.

Hey David, did connecting the battery to the 12-volt accessory circuit in the 1:00 pin position work out for your trailer lights? I'm curious because it could help others with similar setups.
