Could some point me in the right direction, or look over their mega fuse panel on an LMM and tell me what wires are where. I changed mine around years ago to make room and really wondering if I have it setup any way at all like it is supposed to be lol.

If I remember correctly as I rewired my power wires on my truck. The top is the power to underhood fuse box, middle is power to the grid heater, bottom goes to the GPCM. I Moved my fuses to the driver side fender since I only run one battery and no longer have glow plugs or grid heater.

I'm not a 100 percent but I think it is the bottom right. Do you still run both batteries, glow plugs, and intake heater? If not I'll send you pictures cs on how I redid my setup for a single driver side battery

Ah ok. I only run one battery and moved all my wiring to the driver side fender. Ran a single 2g wire from the battery to the starter. Don't have any problems starting unless it's below 30 degrees out. I don't drive it much in the winter anyways.
