Yes, I've searched for the past 2 hours or so. I cannot figure out the best method to go about setting up the fuse block / relay system. Never done this before, so if anyone can guide me please do. My plan from what I've read this far: 10ga hot coming off batt to a fuse block. 12/14ga coming off that to individual sets of lights: - 2 hella 550's on the bullbar to a switch - 4 LEDs on the roof wired to a switch - 2 led spot lights out back to a switch - 1 winch line dedicated to switch - 1 switch to interior compressor located where factory sub was My questions: Each "set" grounded individually, with in-line fuse or is that necessary since I'm running a master aux fuse block??? Best fuse block source (west marine?)? Best gauge wiring? Best ground source? Would I need additional relays? Where?
