adding above. purchased a clip in unit. ref was a 1992 Chev Camaro V8. i will need the female harness(2 prong). any suggestion as to what source i could purchase? gmpartsdirect does not have on website. think NAPA or autozone checker may carry?
hate to go to GM dealer!
also which color lead on harness goes to ECU? is the other lead ground or a voltage source? i will assume voltage source. if voltage where would one locate a source?

 

Ron,

I got mine from Lee Auto Parts. I used the ZR-1 open ended sensor and got the pigtail for it also. It doesn't matter which lead you use. On mine, one is spliced into what used to be the EGR line to the ECM. Make sure you change pin config for EBL. The other lead I tapped into TPS ground wire. You'll find that in the harness running on top of the pass side valve cover.

 

thanks. i most likely will get the harness locally. the air solenoid (not used) is the one geekybill suggests on his website (pin 14) so will use it. he provided a connector and lead for me.
