What I would do is I would first put it back the way it was then go out and pull both of those loose then turn the key on and ground one and see if the gauge pegs

IMHO

Just randomly grounding things I disaster waiting to happen.


Red dots are 5 to 6 v from the IVR in the fuel guage

Blue dot is the sensor input for the temp guage

Magenta is sensor input for the oil pressure gauge

The hole by the word "Red" and the hole up and to the left of it is for the ammeter.

Yellow OR white is the 12v feed to the IVR inside the fuel gauge. (I don't recall which) the other is the fuel sender feed.

This is NOT a resister. It is a capacitor to reduce noise to the radio from the contacts in the IVR inside the fuel gauge.
