Just purchased a new yamaha trim gauge (Ebay), looked to be the same as mine.

Block connector on new one is 4 spade mine is 4 plug.

My old one has 4 wires out the back ( setting aside the bulb leads )
Orange/grey/pink/Yellow/black (black comes off to a Y).

New one has Yellow/Pink/Black (black comes off to a Y), again setting aside the bulb leads wich are blue and black.

I can fit it all up but still left with the grey and orange, does anybody know were they should go?

Not sure if this help but Im 99% sure that pink is for fuel. So that kills one wireOut for ya.

Thanks for that!

I will have a look in the morning, but if i remember correctley the pink/grey/orange/ and another (black or yellow) comes strait from the trim sender unit.

black is sender ground,orange is sender 5 V reference, pink is sender pickoff voltage and gray is the visual indicate for an overtemp if the guage has the indicator.
