Struggled with finding a location for the fuse box to where I wasn't worried about chafing, moving parts, or access to fuses. Finally settled on a decent spot, I can get to all the wires easily and all the fuses/relays are in plain view as well. I couldn't figure out how to mount the box. I'm unfortunately going to wedge it under the dash and securing it with zip ties. I can't figure out how to separate the box halves to gain access inside, so I don't know of any safe spots to run zip screws through. There's not enough room under the dash to incorporate the original mounting setup. Finally, I'm not smart enough to figure this out in a timely manner. With one 1/8" zip tie I can rock it with my full body weight on it and it does not move. I will be using larger zip ties, rubber hoses on sharp metal edges, this thing will be solidly mounted.
I had to swap the wiper and headlight switch locations on the dash, but that's the extent of it. It's not going to be pretty, but it will be fully functional, out of the way, and out of mind. It uses the steering column support rod as it's main hold, there's an upside down c-channel on the inside lip of the dash that the box mates to like it was made for it. Any more downward angle and it would start to interfere w/ the clutch pedal.
Looking through dash where gauge bezel mounts, wire bundle will cross over steering column, have a stress relief @ the defroster duct, then angle down to the grommet in the firewall center. I've already put 1/2" hose on the upper left corner so it rests against the cowl tray w/o scrubbing it w/ the hard plastic.
Look through w/ bezel in place, already beating up my paint on the dash.
Looking up from the floorboard, not 100% ideal, but can still easily access every fuse and relay for future repairs.
Looking through the backside of the gauge bezel, you can see the clearance I gained by swapping wiper/headlight switches in the bezel. This will NOT work with stock gauges. Luckily the trailblazer gauge setup is shallow and will work.
How the switches look, I will fix this in the future, right now it's function over form for the time being.
