So this took a while, but the end result was well worth it. All the aux wiring is done!!
So, i bought a relay box off amazon:
Switches are from OTRATTW. Locker, line lock, light bar & winch control switches installed:
i bought 18ga 12 conductor cable from Show Me Cables to wire the switches:
Wiring up the fuse/relay box:
I have one standalone circuit for each accessory, plus one spare already run from the box to the dash, so if i ever want to add another switch, all the wiring is already done.
Everything is color coded; the switch wiring is color matched to the individual +12 for each accessory so i cant mix up any wires. There is also a key-hot power source turning on 2 of the relays; one is for the OBA system, and the second is for the elec fan, so i dont have to worry about remembering to turn either on.
At this point, every accessory has been wired and tested for function.
