78 cutlass engine wiring diagrams?

[Smokes442]

I need to find any wiring diagrms for the starter/ignition on my 78 cutlass, looks like there was a relay in the middle upper firewall if i'm not mistaken, I think i found the dist. wire, but need to find the starter wire/wires, came with the 260 V8 olds

Thanks. 3R47F8M577356

Starter wires should be 2 red and a smaller purple wire.
