This is what I did before changing all my wiring to the Ron Francis box and harness.I pulled the main power feed from both sides of the junction box(at firewall).I drilled through both and fed a thicker gauge power wire direct with an inline fuse.Depending on the condition of your wires,this maybe just a temporary fix,as you might run into issues with other old,worn,spliced wires.Good luck Josh,don,t ya just love wiring gremlins.:D
