I have a '88 GT with a 3800 SC Series II from a '99 Regal GS donor car. It is an older swap, 10 years or more, that I purchased last year. The swap builder also installed the '99 Regal gauge cluster, which looked very bad, so I am replacing it with stock Fiero gauges.
I am trying to get the Temperature gauge working correctly. I am thinking the '99 3800 SC engine may use both a Temperature Sender/Sensor for the gauge, & Engine Coolant Temperature (ECT) Sensor for the ECM.
The only sensor that I have found so far is on the rear (trans. end) lower left (bulkhead side) area of the intake manifold, that has a Green, Black & Yellow wire harness connected to it. It is a round 3-Pin sensor.
Does anyone have photos of these two sensor locations for the Series II 3800 available that you can share?
Thank you for the help on this one.
