1996 Geo Metro Schematic Needed

I just purchased a Metro that used to be a pizza delivery vehicle. The under-dash wiring looks like spaghetti. Some wannabe tried to install a stereo and made a hell of a mess. My problem is that there are so many disconnections and cut wires, I may need to start at the battery and work my way thru to the taillamps. Most everything works, but the heater motor and the brake lights are giving me problems. Also the back up lamps, but I haven't gone underneath just yet. Does anyone have a link to a schematic that they could pass along? Any help is appreciated.

autozone.com has wiring diagrams for Metro's up to 1993. Look under Repair Info and choose Repair Guides.
