It's been a year since I've had the car together but I don't recollect the connector in the picture. On the passenger side, it's with the others, the iac, tps and temp sensor and looks like a injector connector, pink and brown wire. All nine injectors connectors present, accounted for and in the right place. Traced the wires back to the harness, doesn't look spliced in, what am I missing?

 

Its a intake tempature sensor located on the front of the tpi intake . Its square so it should be easy to locate

 

maybe not, from this thread (https://www.thirdgen.org/forums/tpi/...nsor-part.html) looks like it's a cold start switch?

 

clicks onto your intake manifold in the front.

 

its the sensor in the lower corner, the brown one.

 

Now I get it. And the HSR won't be needing it so problem solved, thanks guys.
