Got troubles with the trim gauge! It don't work and I can't find a "sender" on the motor. This is the first boat I've had that has tilt and trim so I'm behind the eight ball on how the gauge gets it's signal!

For reference I've got a 1987 Johnson 88 Spl. Where should I be looking for the "sender", and does it work off the same principle as a fuel gauge?
