I bought a 1T 1975 C20 dually earlier this summer that's got some quirks and non-working systems that I'd like to fix - but, I can't find schematics for either the wiring or the engine compartment. Anyone out there able to point me in the right direction? What I need to do is: 1) figure out why the cruise control doesn't work 2) get that brake light to finally turn off 3) see if the aftermarket a.c. is functional or if I can hook the original heating/cooling system back up 4) get the fuel gauge to read the right hand tank or install a separate gauge for it 5) determine why the windshield washer motor doesn't work and replace it if need be What I don't know is: what all I'm looking at under the hood or if I take off the dashboard! I'm great at reading maps, know which are the business ends of a screwdriver and wrench, and am willing to attempt any of these projects myself - I just need to know where to start looking, and what to look for when I get there. Thanks!!
