Here's a link to the other post. No, don't have resistance values as yet. What I am pursuing is finding the original GMC gauge (either part number or unit) and an original sender(same). Then if I am successful, I can measure the ohm readings at at least three different temperatures. Then I could post them so others could measure the senders they have to see if they are within a reasonable range to work with the gauge. The best scenario would to be to identify a current part number of a sensor and people could buy that. Will keep on working at it.
