I heard that Shannon at Redline Gaugeworks says you can add a resistor inline to the aftermarket temp senders to get them to read correctly.




I added a 10 ohm resistor to my temp wire as it goes into the harness near the sender [you don't see it as it is only an inch long]. Solder it in and wrap with tape to match.

I used a parts store sender and it read too high [temp]. Tried a couple resistors and the 10 ohm was correct for my guage to be accurate.

Don't forget to verify your actual water temperature when you try different resistors.
