Want to hook up a tach, my boat mechanic said it would be a "grey wire".....he thought off the main harness up by the controls.....I was wondering if it could be this unused plug on my motor, the black plug in front of the big red harness plug in this pic, it has 3 wires the go to?? One is grey

That connector is for the VRO. Must have been disconnected. Your mechanic is right. There should be wires for tacho and trim-gauge at helm end of harness. Trim-gauge use black, red and white/tan wires. Tacho uses black, red and grey wire.

I believe that Nordman means purple wire, not red wire in the previous post.

Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.
