i have a 1996 jeep cherokee se, with a 4.0. im having a problem with my ect circuit. i have no temp indication on my gauge. i have already replaced the thermistor and have received no satisfactory results. i have tested cavity a16 to the sensor and its fine. i have also tested cavity a4 and have a good ground. i have a service manual from jeep, but i cant find any wiring info from the pcm to the actual gauge. at this point i would love any info that would give me the points to check the gauge to the pcm.
