so I'm in the process of building a roof rack and just trying to plan ahead here. I'm planning on running 5 100 watt lights (pick any brand) on the front of it. I wanted a clean wiring install so I got a factory overhead console at the junkyard and gutted it. I plan to skin it with some sheet metal and paint just so i have plenty of room for switches, cb, dome light or whatever else. I plan on getting a fuse block and a relay holder/block from the junkyard and rewiring it for just the lights for now. I plan on mounting those up inside the overhead just to keep it out of harms way.

My question is this, would a single 4 gauge power and ground run to the battery be enough for say 3 small fuses for the switches 3 bigger fuses for the relays and 3 dual 87 relays?

I just want to cut down the number of wires i have to actually run to the overhead.

 

maybe run the single post and neg wire to over head and mount the fuse block in it that way you are only running two wires to it

 

thats what I was thinking. but do you think a 4ga wire would be big enough to support the fuses, relays, lights, switches, eventually a cb and whatever else I can put up there?

 

i would think so as a back up pullthree wires and dont connect one for back up 12v source

 

Good luck getting 4 gauge wire up the overhead counsel.

 

freegdr- thanks for the idea, never even thought of that

91 limited- it aint that big maybe 3/8's across at the widest

 

ill send you my bill lol
