Hey everyone. I was wondering if any of you had access to a wiring diagram for a 1977 Pontiac Catalina - yes, I realize this is a Firebird forum, but on the off chance that someone might have one, that'd be great. I need one to install a tachometer in my car - I don't know where I can find my RPM information to hook it up. Thank you, and again, sorry for a non-Firebird question here.

We have the 78 Pontiac service manual in the 2nd gen tech section. It should be close enough to 77 to help you.

If you insist on 77 Pontiac service manual, I think you can find one @ http://www.78ta.com

Back in the 60's & 70's Pontiac made 1 service manual covering all their cars.
