Ive got a 53 1/2 ton p/u and I am replacing the vacume wipers with electric. I already have an after market new 12 volt fuse panel and the only place I am getting power that is on an available circuit is the radio slot. I currently don't have a radio in as of yet so I can use that temporarily but I need to know how I can use more of the panel. There are empty slots, but no wires
going to them. I assume I need to run some but don't exactly know how to get to the innards of the fuse panel. Do I need to take the panel completely off the firewall to get to them? Any help would be appreciated.
