where is my temp sensor
I recently took my 90 yj and installed a brand new motorcraft carb. now i am not getting any reading from my temperature gauge. both sensors on the side of the intake manifold are in good shape still but the sensor on top of the manifold right in front of the carb was broken. i looked online to find a replacement but could only find the temp sensor on the side of the manifold, not on top. Is the broken sensor my problem and what is it. Where can i find a replacement.. trying to upload a photo

Welcome t JeepForum, you've just found one of the best jeep sites anywhere! :wave:

Far as I know jeep uses 2 temp sensors, one for the engine and the other for the gauge. The sensor for the gauge should be near the back of the head on the driver's side, right near where the manifold bolts on. Purple wire on it if I recall correctly. You might also check to see the gauges have a good ground, bad grounds a very common prob. Hope that helps!
