1992 Chevy K2500 wiring diagram

hi everyone - new here - hopefully you can help me out.

I just bought a 92 k2500 truck and am trying to get the interior lights and radio working - seems there was an alarm/ remote start unit installed in this truck at some time and was disconnected because it was malfunctioning and draining teh battery before I bought it. Now the radio and interior lights do not work.  In an attempt to fiqure it out I started following wires and removing disconnected alarm stuff to try and clean it up. I have found that the radio is somehow attached to the alarm/remote start wiring and that is likely the reason it does not work (there is no power and the fuse is fine). one of the radio wires has been rerouted through one of the harnesses that connects to the alarm module - which had been disconnected.

So I'm looking to find a full interior wiring diagram so I can remove all the remove start wiring and put things back to orginal... Or if there is a better thing I should do I'd love to hear that too.

Thanks in advance.

Hey,

I'm in the same boat - or I should say truck.  I have a 92 K2500 also that someone had decided to do some creative wiring.  I also could use a hand with wiring schematics or whatever someone has.  Please help!
