    Still need info on wiring up those lights? I can shoot some pics tomorrow if you want. I ran the wires down the rain/drip rail and in right where the top fits up to the cab. There is just enough room to get it through without causing a leak. I have had it like that for about 5 years now and haven't had a problem.

    I ran three relays. 1 for 2 of the round top lights, 1 for 3 of the top square lights, and 1 for the 2 front round lights. I have a total of 3 switches.

    My alternator was upgraded a couple years ago. I don't remember the size but it is bigger than stock I know that. It needed to be for running the winch, all the lights, and my stereo.

    I drilled a hole in my roof and filled it with silicone. Just pull the wire under your headliner.

    As for your altenator... I bought a powermaster 140 amp altenator from advance for around $160 to $200, I don't remember (the chrome one was more, so I didn't get it). The specs on it from what I remember were something like 90 amps at idle and the full 140 at, I wanna say, 3000 rpms. I don't remember where I put the specs tag that came with it, where they have a altenator dyno they hook em up to before they send it to you. I haven't had any dead batteries yet (from altenator issues anyways) and I run 4 100w lights, electric fan, and now a stereo with two speakers (:woot: ). I know that Summit sells the powermaster line and their own line of up graded altenators all the way up to 200 amps I've seen.

    Here is a shot of the relays and fuse panel.
    Next is a shot of the whole truck.
    I noticed in the pic of the truck, it no longer has the lights below the bumper. All of the others are still there.
