Started putting the wiring harness back in my Ventura and having troubles with the TI harness. Does anyone have good wiring diagrams for a US Pontiac. The diagram in the manual does not match all my wire colours and the TI diagram is really hard to make out. Hoping to fire the 421 when I get back from Florida. I even bought a wiring diagram off eBay but it is just an enlarged copy of the diagram in the book
Bill.. I would call Dave Fiedler from TI ignition repair in Indiana. He should be able to help you out.
I have some experience with TI in Corvettes. Remember... the wiring harness can not be altered/cut. The length of the harness is part of the resistance needed to make the system work..
