Exactly like on my JDM...

This is very interesting... I would assume that a healthy gauge would peg to the top with the sender wire grounded! The mod then would require modifiyng the gauge meter in such a way to increase deflection, possibly by reducin tghe value of a resistor inline with the movement itself...

Exactly my point... Anyone with a spare dash gauge they are willing to offer for research?
