I have a 93 ZJ that I just finished swapping a 97 XJ 4.0 into. On my ZJ the ECT sensor for the guage was on the back of the head, and the sensor for the PCM goes into the thermostat housing. The new engine (from a 1997 XJ sport) does not have the spot on the back of the head for the ECT sensor to attach, and I can't seem to find anywhere that it does attach. Can anyone tell me where this sensor on the 97 4.0 is for an XJ? Any help is greatly appreciated!
Thank you,
Mark
