    I'm looking to add some accessories to the interior and exterior of the truck over the next few months like gauges, bed lights, interior lighting, etc.

    I would like to have one junction box under the hood and one in the cab so that I can easily connect 12v accessories to it. I do not want a nest of wiring running all over the engine compartment and 6 connections to the positive battery terminal.

    Ideally, I'd like to have just one cable coming off the battery, have it relayed so it is on only when the truck is, and split to the 2 junction boxes. My thinking is that if I relay the main cable I won't have to tap relays for each accessory separately.

    Can someone recommend a good junction box for this purpose? Whats the best way to go about doing this?

    -Thanks!

    Look in a marine store. They have really nice weather resistant fuse/junction boxes that work great for this.

    could you tap into the existing fuse box for an accessory power to provide power to the fuse block you add? or would this overload the fuse tap in the fuse box?

    Thanks 86ceteen, I'll check out a marine shop when I'm in Occoquan next. There's a marine shop close to the river.

    Carson, I don't know much about the math for figuring out electricals, but I doubt that I'll be running much power. It'd be mainly for lights in gauge pods and accent lights. The highest draw would be the bed lights. Still, I would rather have these on a dedicated circuit than piggybacked onto an existing fused connection. I could use an existing fused circuit for the relay input to switch on all the other accessories.

    ahh makes sense.

    i just figured seeing as how the fuse box has some extra fuse locations that are not used we could tap into that to power the fuse block. im looking into the same thing but was a little skeptical about adding that to the fuse box in fear of popping some hidden main fuses or something.

    post up how you go about adding a relay to this i was thinking about doing this

    just use LEDs....they use VERY little power and you don;t need a relay!
