Im restoring a 78 from bumper to bumper. So far I have raised the body, sanded, primed and repainted the entire frame (I hate rust). I have completely rebuilt front and rear suspension including trailing arms. Also I have rebuilt the power steering cylinder and attempted the power steering valve but mine was to far gone and had to be replaced. I have traced and repaired the entire vaccuum system ( heat/ac, headlights, cruise control). I am now moving on to electrical and other systems, and  engine components are in machine shop If I can be of any help with anything mentioned above please ask. I feel like I know these systems intimately. 

I saw a thread on here about wiring diagrams and would love to get my hands on anything available, specifically cruise control and alarm systems. Also have wires I cant identify. where's the best place to start?
