Temp sensor question

[SNKSKIN]

I have a 96 Mustang gt, which had a 01 cobra engine transplanted before i bought it. I found out that the cobra engines went from two temp sensors to one, but which is the one that feeds the pcm to kick the fans over.

I only know of the one on the intake manifold. I was not aware that the modular engines had 2.

For the 96 MY, the PCM ECT temperature sensor uses the LG/R and GY/R wires. This is the sensor that tells the PCM the motor temperature.

The dash temperature gauge uses the R/W and Y/R wires.

The two sensors are NOT interchangable.

For the 99+ MY, a single ECT sensor is used. The PCM tells the dash what temperature to display.
