I have my fuse box attached to my glove box door. I made a plate that attaches to the insde of my dash next to the glove box that houses my grounding strip and voltage regulator.
It was a lot of work but I know how every wire is run in my car and I was always afraid of wiring. I enjoyed it. Especially when people comment on how clean the wiring looks.
Best of luck with any kit that you use. I think painless and American autorwire post the instructions on their websites. Check them out.
