stereo wiring

[hpotter]

Hi, I have a 94 camaro and I went to change the head unit only to find out that the guy before me had cut the harness. It's not that big of a deal because I wanted to run new speaker wire anyway; but my question is does anyone know where the power, ground and accessory wires go to? Are they part of the main harness or do they go somewhere else, possibly the fuse block? I am asking because the previous owner cut the wires so short you can barely reach them and I'd rather run new wire then trying splice them together because I intend to run the wires to a new plug so the wiring is back to the way it was and I would rather not have any spliced sections of wire. Thanks for any help.
