Hello. My trim sender broke. i purchased a second hand one. the only difference between the two is the old one was 3 wires and the new one has 4. i spliced together colour to colour Black, Orange, pinky but left the grey out from the second hand sender , the gauge didnt alter still shows fully trimmed out . any ideas

There are three wire senders and there two wire senders. Three wire senders are potentiometers. Two wire senders are a variable resistor.

Change from three wire to two wire happened circa 2001. Here in the USA anyway.

If you can physically get the wrong sender installed, and then change the tachometer from the three wire type to the two wire type it should work.
