Anyone know a good source for wiring diagrams? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Been thinking about this and searching the internet, but have yet to find anything.
Everytime a do a OEM conversion, I end up buying the FSM just to get the PCM pinouts and wiring diagrams. My last conversion (the 99 Burb drivetrain into my 71 C20), I bought the Helms manuals directly from Helms. The wiring schematics are terrible. So.....instead of buying the FSMs, is there a source for just decent wiring systems schematics?
Surely someone out there specializes in wiring diagrams.....anyone know of a place to contact?
