2011 Georgetown 350 7 pin hitch socket
I am looking for some help with the location of the fuse supplying the hot wire to the 7 pin socket on the back of my 2011 Georgetown 350. Specifically, I am trying to find the location of the fuse or breaker supplying pin 4 (at the 2 oclock position) in the socket. The pin is hot all the time even with the key off. The owners manual for the Ford chassis lists the loads for the fuse panel in the cab and the fuse panel in the engine compartment but doesn't seem to include this load. I have removed several of the fuses associated with "trailer / tow" loads but none of these supplied power to this pin. The hot wire doesn't appear to be wired directly to the battery unless it is at a junction I can't see.
I am going to install a charge line to my toad to maintain the Toad battery during extended pulls. I have a Blue Ox Patriot supplemental brake unit in the Toad. I will be using a Toad-Charge unit to regulate the charge and prevent back feed. I want to determine the fuse / breaker size of this hot wire.
Is anyone aware which fuse / breaker (and location) supplies the charging pin? Any info would be appreciated. Thanks
