for you one of the sensors will be signalling your ECM and connected to Pin C10 on the ECM, one will be for the manifold heater (single wire sensor) and the one on the back by the fire wall should be the signalling unit for the gauge (also with a single wire). Glad it helped, old post but useful info.

My gauge has started jumping around a bit. I accidentally bought the sensor that goes into the thermostat housing, so now I've got the right one in the mail, but does anyone know where I can get a new female end? Looks like the previous owner already did a bit of splicing and I would rather just start fresh.

If you are looking for the connector check your local parts house. They should have a solution.

I'm glad this info is here. I almost bypassed the wrong one.
