I tested my gauge. When grounded, the needle would go all the way to the top. When I removed the ground it would very slowly fall back to zero. Hit it with ground again and it would go all the way to the top. It wasn't instantaneous but it was quick. Remove ground and slowly it would travel back to zero.chevyeater said:The easiest test for the guage and wiring is to remove the plug from the sender, turn the key on and check the guage, it should be all the way down. Then, ground the wire and check the guage again, it should be all the way up. If it works like this, replace the sender. If it doesn't work like this, either the guage or wire needs repair.

I had to swap out the sender on my JDM 7M-GTE. The JDM sender was a plug in electrical connector type, that I am assuming it's for a digital dash. You need the USDM sender for it to work.isnms said:I think I read it somewhere, there is a difference in JDM and USDM senders.
Hopefully someone with a JDM swap can confirm.
