Where does the A/F meter harness come from?
 

I have a 964 turbo and i was woundering where does the harness on the air/flow meter go to ? I went to install a rpm switch with my BL WUR and the air-flow meter isn't plugged in. I can't seem to find where the PO stashed it!?!? Better yet I don't even know what it actually does. If someone knows or could feel around where the harness leads to that would give me a great place to start looking. I'm hoping the PO didnt cut or re wrap it into the wiring harness.

Thanks

Anyone?

don know what exactly you mean
are you referring to the blue plug on the back of the air flow plate housing ?
that one is NOT hooked up on a 1991 c2Turbo

Yes that's it. Your the second person to say it isn't hooked up so I guess the testing proceedure on BL rpm switch instructions don't apply to the 965 for testing the system.
Thanks.
