On my 78 El Camino I was able to find a very clear wiring diagram in the
Chilton's manual. I blew it up on a copier and laminated it. Now I have a
permanent - grease proof wiring diagram.
As Bruce mentioned, you can get these from your local public Library. To
again second Bruce - there are wiring kits available for that year.
Good luck.
