I haven't checked to see what the auto parts store can get as far as various lengths of wire without having to spend on 100' spools but I know he can get me the good wire. I know I need 1 color for each circuit + All connectors, relays and fuses.. I was planning on checking the prices before I purchased anything beyond the relay block which will only cost a few dollars from the junkyard.. I have a boat which will need rewiring also, but that entails 2 lights ( Navigation and Anchor ) and a horn if I go back to stock. and may add a VHF and some interior lighting but still, I can't justify having 50+ feet of 10 colors for 5 circuits.
