im installing headers as you read, i seem to have lost the connector for whatever sensor plugs into the drivers side head(is it the temperature switch?) anyways, whatever it is i need to hook it up. i was just wondering if anyone can tell me where that wire ends up going so that maybe i can track it backwards.

thank you,

david

 

GM was horrible abou those temp switches. My car has one in each head...figure that one out. - anyhow, the wire should be green(not sure there), and root w/ your O2 wiring(definit)...

 

thanks for the info, my dad figured it out right before i came and checked this.

thanks,

David

 

I take it your fuel injected then??? one in the pass head is for the fans, one on the drivers side head is for the guage, If TPI the one under the TB is for the ECM. Hope this helps with your curiousity?

On my part...91 TA..yeap TPI.

 

Cruzin Kaz - that explains it. But how come if I unhook the computer one, the gauge doesn't work? - aaa, who cares, my 750 Holley and mechanical temp gauge don't...

 

Good question...Maybe some years were different then others??? Anyone else???
