There are two; you are on the right path there. Off the top of my empty head, the sender on the thermostat housing goes to the ECU/idle circuit, while the second sender on the intake itself runs the actual temp gauge in the dash.

At least that's what my 85 does;I bet yours is in the same boat. :)

The sender on the intake is located lower than the cold start injector, but against the cylinder head... if that makes sense. Standing on the passenger side, the sender is under the cold start where the lower intake bolts to the head.

Shoot me your number and I can get pics tomorrow in better light.
