I have a 1979 starcraft jon boat with a 1970 20hp Johnson when i bought it the wiring was all removed
cant figure out the tilt. Control button has 3 wires and lift only 2. Any help would be greatly appreciated
When you say control button, do you mean on throttle handle or on motor? My initial thought would be the three wires, include a red for power. The red probably meets up in harness or solenoid/relay somewhere and then gets directed to the trim relays. The green and blue are your up and down trim wires. The two from the motor seem to be your basic power/ground combo.
