There is/was a wiring diagram on suicide doors website. It was simple to follow, and even showed pictures of compressors and relays...etc. It would be hard( but not impossible )to screw up using it.
I would recomend running a 4 guage wire just to be certain the current draw, and voltage drop isn't too much for the length of wire.
Good luck
Oh yeah, sorry I'm too lazy to look for a link at near 4 am...lol
