<strong>Yahoo Message Number: 78395</strong>My CC manual shows pin 4 (Black wire)on the tow socket connector as being "charge". I am having difficulty finding this on the wiring list. I want to use this to charge a battery on my trailer which is used by the mover, so I need to understand how a charge feed goes through this pin? From where? Is it fused? Where is the Fuse? What amps can...
