I am trying to find the wire that should be routed to the 7 pin trailer reciever to supply power to the trailer battery.My Dodge 1/2 ton 4x4 has a partial tow package factory installed. There is a 40 amp fuse in the power dist. box that is marked as Trailer that leads to the Trailer relay which is also in the power Dist. box. From the relay there is a 12 ga. Black with orange wire that I am assuming is the charging lead going into the main harness. Any ideas where this wire terminates. I have a Haynes wireing schematic for this truck but it does not show it anywhere. Thanks in advance. Oz
