Firewall tach hole location
Can anyone show me a picture of where the factory tachometer hole is located on the firewall of a 1972 truck without A/C?
Thanks, Jeff

Re: Firewall tach hole location
Chris,
The harness with grommet that is above the tach harness, what exactly is that? Is it the harness that runs to the carb on 71-72 emissions trucks? Jeff

Re: Firewall tach hole location
I think it's the one that controls the trans when it's cold, I can't remember the correct name for it. It has a flat connector with three terminals on it.
