wiretap,
This is a great tutorial. I was wondering if we could go one step further...
The lead on the power module is 4' long, and the fuse is built into the casing. Shouldn't we just be able to cut off the plug on the end, and attach the vampire clip to the bare wire ends, thus negating the need for the additional socket? It's pretty tight under my center console/emer brake cover, and I don't know if I can squeeze the plug and socket. It would also allow me to drill a smaller hole in my glove box, since I wouldn't need to pass a 1" wide DC plug through it.
EDIT: Found a detail
