I had a JDM itr cluster in my 97 LS db8! The gas gauge was jam! I bought a 00 gsr cluster n installed it n gas gauge still doesn't work!
I swap out the green film in the back n now the gas gauge went all the Down pass "E"! N my temp went all the way to "H"But everything else is working
Just wonder if I need to switch some pins up!
Any info will help out

 

Bump need helP

 

Updated!
I got the gas gauge to work. The pins in the harness wasn't connecting!
Now my temp gauge is wrong!
I turn the car on a cold morning today n the temp gauge shoots to "H"

I check the connction in the back of the cluster n every seem good!
Could a thermostat went bad!?

Any info would help!
Thanks
