I stumbled upon a really informative site for some of our topics. I found it while I was researching relay wiring. http://www.the12volt.com/
Anyway, I'm sure many of you know of it. I did a search of the board and only found a few posts that ever referenced it, so I figured I put it up here for the Newbies. It has all kinds of info relating to installation of almost everything (exept car-PCs) including good information on wiring, fiberglass, and many other topics that often come up here.
