Complete wire diagram

[fnny6770]

I have a 1980 GMC k3500 Sierra classic camper special, I would like to find a complete wiring diagram to this truck, some of the ones I found look clear from a distance but when you zoom in they get all blurry, where can I find a decent wiring diagram?

Thank you Ricko! I assume CK is C and K series trucks, G is van. What is ST and P refer to in the wiring manual? I don’t recall these series light duty trucks?
