Wiring Round 3
I need to stop this madness.
Just recently I tore out everything - Bussman relay box, all the cool wiring I did, ditched the AOB switches, etc etc.

In preparation for my fridge, water pump, water heater, air compressor, and other future toys I decided to repurpose the bussman relay box to the rear and use the SPOD for lighting and winch control.
To get things started I needed to plum some wire through the firewall. I found two locations near the master cylinder. The negative side already had a grommet but the positive side required drilling a new hole. The grommets came from ceautoelectric supply and offers a water tight seal and protects the cables from coming into contact with the firewall and possibly shorting.
Once through the firewall I routed the 4AWG neg and pos cables along the door/foot area. I also have a few relay control wires as well. Something to note is two sets of 4 AWG is the MAX you can fit here. You can easily fit one 0 AWG wire as well if you decide not to run a dedicated ground.
Getting the wires to the rear took a bit of time due to the wires fighting against me when I tried to route it over the rear wheel well. Be sure to use some wireloom here on the positive cable as there's quite a bit of sharp edges in the wheel well area. Also, if it's not obvious, you will loose your bottle jack and jack tools doing this mod. For the majority of us it's a non issue as I'm sure these things become useless once we're lifted and have bigger tires.
Moving onto the front I prepped the SPOD with some Delphi connectors as I wanted a way to easily remove the SPOD in case I needed to access the fuse box it sits on or if I'm in an environment where I believe it'll get wet (water crossing)
Been asked spod vs switchpro and I gotta say I did it for the screen and the ability to mount it in the cup holder using a 3D printed cylinder.
Now the biggest headache. Wiring! I made some custom battery cables to send juice to the spod, fuse box, 250 amp circuit breaker. I also had to redo the chassis ground for the battery amp meter that I riveted to the Pelfrey battery cage. I'm not a fan of all the wires but honestly there's just no other way
Right now I'm working on finalizing a piece to house the battery gauge and spod. Right now I have something finalized in aluminum and seeing if I can live with it. I also got to wire up the fridge, pumps, etc in the rear but that's easy since the hardest part is complete.
Will have more later!
