HAC sensor and A/C temp switches

[scotty]

Hey!

Doing my GE GTE swap.. and I've now got HAC sensor and A/C temp switches connections on the harness. But as far as I know I don't have the HAC sensor unit, and got no where to connect the A/C temp switches.

Do these two have to be connected in? Would I have to buy a HAC sensor unit?

Thanks

This is not a simple question... the HAC sensor was exterior to the ECU only for the early model GTEs, then in '89 it was moved into the ECU itself. If you are putting in an early model GTE harness / ECU, then yes, you'll need one of these sensors.

Hopefully someone else will chime in about the AC.

Thanks! Just bought a HAC sensor, so that's sorted then.

A/C hopefully isn't that important.. only goal is to have the car running fine.

That A/C plug goes to the ECU with the pigtail.

No it doesnt. The pigtail coming out of the ECU has a larger connector.

Did you find where this plugs in? I cannot seem to find the connector.
