Defi Gauges

Hey guys I just put in a defi water and oil temp gauge with defi link controller and for some reason the oil temp reads up to about 90 degrees and it starts to jump everywhere and the water temp gauge just dances… anyone have this problem before? the worked on the car they came out of…

im guessing something is up with the sender units to the gauge

or the ground is shitty perhaps

I would definitely try grounding the senders better. I had the same issues, once i grounded them better, no more issues.

i’ll try these things… if you get some spare time you wanna pop up chris and check the install… maybe there is a better place to install…
