I need to re-wire my TIM water temp gauge. It has 3 terminals on the back labelled - "S", "G" and "I" or "-" depending which way you look at it! Any ideas which is which please? Clearly one is +ve feed, one is earth, and the other is the sender.
Thanks
Dickie

it could be
S sender
G ground
I ignition
but dont take my word for it
