Wires, switches and more insulation

Just 12 Volts, +positive and -negative. Twisted four wire, untwisted 5 wire, 14awg & 12awg, 8awg fuse block feed, 1x30A, 1x20A, 2x10A & 2x5A circuits, 500A magnetic combining/isolating relay, and a 100A fused secondary battery feed. Simple, right?

I started with shooting a pull string for each run of wires, which is a trick in and of its own. Both pull strings in place, I set up my spools of wire, taped the ends together, attached them to one end of the pull string and began pulling my runs. Pulled about 5 feet extra for each run just to be sure I wouldn't short myself later when branching off the individual circuits. Next was time to run my main feed for the fuse block. This was done outside of the overhead support ribs and attached with P-clips because of the fear of cutting the wire sheathing on the sharp metal edges. 
Feed wire in place; next I installed the fuse block, switching solenoid and the main 100A fuse.
Next to wire the fuse block according to my wire map and color codes.
... Yes, chicken scratch.
And we Spray foamed all the voids with more insulation!

Protect them wires!

Always pull extra!

Oh and that extra insulation...
