On the blue pin connector,

25 brown wire ECT ground
Third wire goes to gauge

Any chance you can tell me the position of these wires. I'm using a GM TPS sensor plug I stole off a salvage yard car and the wires colors are different obviously.

Thanx

brown top left (ECT ground), yellow top right (ECT signal), gauge wire is bottom center if you decide to use it.

Thanks.... I assume that's looking at the sensor side of the plug.

, The third pinout is a thermistor right. If so, anyone know what the resistance is at ambient temp?
