Custom Power Distribution Block

Ok here is what I came up with. Btw everything is covered in looms and buttoned up itís just easier to see when all the wires are exposed. This system will allow up to 6 circuits running 150 amps total or any single circuit running up to 30 amps. Typical set of 130 watt lights draws around 22 amps.

I started with my switches in the dash. I have not placed a 6th switch yet (Iím going to put it in the a pillar for a fan cut off) but I put in my 5 like this
Then I tapped into the M8 fuse in the fuse block designated for heated seats. This is only live with ignition. I piggy backed off of this with a 10 amp fuse and ran it into the cab and into this distribution block.

I ran a wire to each switch. Then for ground I drilled a hole in the aluminum frame and installed a grounding stud, again running to each switch. Now each switch will come on only if the ignition is on. The red wires leading out to the engine bay find there way to a bank of relays attached to a Rockrash4x4 relay mounting plate.

there is a fuse block attached to the plastic wall beside the battery.

I used a 4ga battery cable to power the fuse box. You can see it in the relay pic. If I did it again I would grab power from the terminal in the fuse box instead of the battery for a cleaner install. Each line is then fused and sent to the corresponding relay.
Last order of business was to ground the relays. I ran each gound to the relays tapped mounted bolt, then grounded the entire plate using the bolt on the inner fender well right by the fuse box

Now if I want to throw another set of lights or anything else pulling less than 30 amps all I have to do is hit one of the open relay terminals. My only concern is the new aux fuse block being open, but Iíve installed low amp fuses in all the ďemptyĒ spots, and they fit very tight in there. so far it has not been a problem (Iíve been running this for about 2 months) and Iíve run through lots of high water recently. Thanks to Ike and my need to explore. Including switches, relays, relay plate, wires, connectors, looms etcÖ Iíve got right at $90 invested. And getting to the factory fuses works the same way as before.

that looks nice. I need to make one up for mine.... too much crap running around behind the dash is starting to get on my nerves. If I add any more power stuff I am going to need to make happen.

Good pics (and I am glad that you trim the cable ties....)
