So I have my original sender from the 74, reads 244 ohms at room temp. I installed it with the 93 wiring and gauge cluster and the temp gauge reads about 1/4 not running at room tempature. No coolant and hasn't run in a month. So I figured I needed a newer sensor, got one spec'd for an 89 and it reads 196 ohms at room temp. Gauge reads about halfway, same conditions as before. After much ado I found one for the 93, what a PITA, anyway it will interfere with my fuel line so I'd rather not use it. If I knew the specs I could just add a resistor in line to rectify the condition. So any one got specs on those senders?
