Hi:
Truck: 76 C-20 with 350, TH400, A/C, stock wiring except for addition of trailer electric brake controller and 6-way connector on rear bumper for trailer.
I am adding a breakaway switch battery to my trailer and so I need an accessory power wire(+12VDC) from the truck for it to charge. Where is the most appropriate place to get this power from? Would it be one of the terminals on the firewall junction block?
I am thinking of running a 12AWG wire with 30A in-line fuse from the firewall junction block to my trailer connector.
Regards,
Henry
