I have a 1989 Chevy Blazer I have spent the past two years building. I have added a chrome tubular push bar on the front of the truck and attached 4 off-road lights. I need to wiring in these lights but I have a few questions. I realize I need to run at least 2 relays for the lights. The lights are 100W so they should pull about 8 amps each. Now here comes the question. I want to run these lights to a (one) three way switch. This switch will be used for Off/On/Highbeam On. Got your attention now huh? I want to be able to wire my lights into the high beam switch. How can I do this successfully? I have located the wire for my high bean and now need to know the best way to preform this action? Do I need to upgrade my stock alternator to safely run these lights? Do I have to purchase a seperate fuse block to safely wire these light in or can I simply use an inline fuse? If so what size wire should I use and what size fuse? is the best place for the relays close to the power source like I have read in some forums or does this matter? If it does matter where would the best locations be for the relays and the fuse(s)?
