I have 2 jdm clusters for my 89 240sx with an sr20det. Iv tried both of them and neither of the temp gauges work. Anybody know a site where i can go to research this problem or anybody had this same problem and know what i can try to fix this.
A lot of times you will need to ground the sensor location in order to get a proper reading. This is especially true for coolant temp sensors in rad hoses.
