Okay guys,
I know that I installed all of my gauges a while back but I was in a hurry before SuperStang Fest and never got my Air/Fuel guage hooked up. Since then I've been busy and just got around to calling Autometer and seeing if I needed some sort of sensor to tap into the exhaust pipes. This was there response:
As for the a/f ratio gauge, you can tap onto either of the primary (pre-cat) O2 sensors. There is no special sensor needed. Pin #28 of the middle PCM connector is a gray wire with a light blue stripe and is a useable signal wire.
So my question is, can someone tell me exactly where to see this Pin #28 on the PCM. I'm confused. Do I just tap into that wire once I locate it? Sorry if this is a dumb question, but I've never messed with the PCM before.
A picture would be nice to help us mechanically defecient ones.
