it's on the glove box support (at the bottom, where the glove box bolts in).
It's a sensor with 3 wires going to it.

That's what he needs. The question is, does he have an internal to the ECU HAC, or an external one? 89+ has all been internal so far. 88- is MUCH easier to wire up.
thanks guys you have been really helpful. i feel so stupid because the stupid thing was right in front of my face... lol
i still cant figure out witch freaking fire goes to the ecu.... im looking through all my wiring diagrams on the tsrm and cant find it...

The online TSRM is for 1990, which has an internal HAC sensor, so you won't find it in the on-line manual.
You can find the pin diagram for the '87/'88 ECU though which will tell you what ECU pin you need to connect.
