I have the Haynes manual that covers my '82 truck and have found the wiring diagrams in the back to be accurate and invaluable because the PO gutted the wiring.  Try the Haynes book.

Well, if you bypassed the relay and it started then you probably have a bad relay. Try swaping it with one that you know works.
