I have a 91 guage cluster in my 1975 c20 ls swap 5.3l

I just wired up the 3pin temp sensor.
The gauge for temp on cluster just maxes out. Need some help with this

you need a temp sender (1 wire) from a 1991 5.7 for coolant temp. stick that in a coolant passage. Dont bother tyring to use a sender with multple jobs. Just focus on the gauge doing its thing, and the sensor for the ECM doing its thing
