1991 grand am 2.5l 4cyl wiring diagram

Hi there, I'm a bit new as you can see but I figured I'd throw this out there. One day I was working on my car with my radio on with the car's engine not running. I accidentally hit the AC on switch and now all of my electronics do not work. I've narrowed it down to being a relay or the ignition switch (at least I think). But, I figured while I have my entire dash out I'd drill some holes and put some grommets in for wires for amps and pretty much rewire my entire car as I have the time and supplies. I have lots of pointless wires sitting around not connected and I have no idea what they go to. I have researched quite a bit for a wiring diagram for all my cars wires but I haven't been successful. If anyone could provide a link or perhaps post it that would be a great help. Thank you in advance.

Im not aware of a website that offers complete vehicle wiring...Im pretty sure Haynes or Mitchell have some on-line programs you can download...but they are not free...! I dont follow how turning on the A/C would cause everything to turn off...When you say ALL the electronics...What else doesnt work...?  It's safe to assume you have checked all the fuses...? Are the fuses for these items that are NOT on still have power to the fuse...Meaning fuse is good and reading 12v on both tabs...? Or theres NO power at the fuses and the fuses are good...?M.E.C.P & First-Class
