Can anyone tell me where theres plugs go and what the other spaces are for (specific info please). I'm look at where i can plug in things because theres a bunch of stuff not being utilized it would seem.

Mines a 95 k2500, this pic wasnt from me, but i think it looks about right but really i've done more wondering than investigating.

IIRC the green wire is bat., the black wire by the purple is ign. the 2 left of it are dead terminals.
