Ohm value of temp sending unit 95 LT1
 

Have the 95 LT1 driveline in a street rod and using a Marshall aftermarket dash cluster that uses it's own temp sending unit (which is not super accurate).

What I would like to do is use the OEM temp sending unit feed wire intended for the 95 cluster and install an auxiliary digital temp gauge.

Anyone know the correct ohm range required for an aftermarket temp gauge display to work with the factory 95 LT1 temperature-sending unit?

Thanks

The Marshall FAQ has some info:

See if this matches the standard GM ohms vs. temp.

By comparing those values last week we learned that the display was off about 12-15 degrees from actual warmed up temperature. I compared the temperature on my OTC Nemisys datalog and the Marshall gauge also.

My son is contacting Marshall to see if they might have better tuned sending unit.

Thanks..
