Hello,

I have a 1J Soarer motor, but I have a Supra Harness. Everything matches up except for one of the water temp sending units. I don't have the car in front of me, but it's located on the water neck and is one wire. The sensor on the Soarer motor has a ovaled shaped with a flat spot on the bottom. The connector on the Supra EFI harness is a rectangular one. I am not sure what this sensor is for. It's either for the ECU or the water temp gauge. I will confirm this tomorrow.

Can someone send me a nice close up pic of these sensors, there are two on the water neck, from a SUPRA? I am not sure if one off a 2J will work or not. I don't have access to a 2J or a Supra 1J motor to check.

If anyone has a spare water sensor they don't need I'd be interested. Thanks for the pic and any info.

Later,

The single wire one is the water temp guage, and the one with two wires there is the green plug, that is the ECU water temp sensor.
