My radio died the other day, and I found the ACC circuit fuse to be blown. It is now instantly blowing with nothing extra connected to it in the fuse panel, so it looks like a short to ground.
Apparently you do have a cat that likes to visit you tho.
This seems surprising to me. I put mine out on the concrete in the sun, and still had to use a heat gun and welding gloves to work it into place.Pro tip everyone.
If you order a vinyl floor made for your truck. Don't take it out of the box and put it in the sun to get the packaging folds out of it.
That same heat will convert it back into a nice flat piece of vinyl...

In the photos of your ammo can mount, there are some silver spacer-type things in the bottom of the can. Those look to be made specifically for the purpose of mounting the compressor in the can...where did those come from? I think my 450c is the same size, I'd like to do exactly what you did, it looks a lot more sturdy than just running the mounting bolts through the bottom of the can, plus I'm hoping they would keep the bolts from protruding out the bottom?
