Trying to wire a tilt trim guage on 2004 F115 Yamaha 4 stroke. The boat did not come with a tt guage, but there is a 2 wire sender (pink and black) and adjustment cam on the pivit shaft. The two wires on the sender go up through the large grommet into the motor housing and plug into a 4 wire harness. How do I get the signal to the guage from the sender? Thanks for help....
