Hi, I just bought a CMC Power tilt/trim unit for my non PTT 90HP Evinrude. I then went and bought a 3 way rocker switch to operate it. I am now looking into how the electrical wiring is hooked up as to reverse polarities for "up" and "down", It all seems like it should be a very simple connection but I am bad at figuring out wiring. Can anyone help me out with a diagram or instructions? Thanks in advance Bill, Long Island NY.
