Welcome aboard.

I think those wires and connector are for tilt and trim.

Need more info from you to give you the tach wire colors. What motor and what is the serial number?

Mercury's newer than about 1978 will use a grey wire for Tach signal, plus black (ground) and purple (+12VDC).

The grey wire will originate at the voltage regulator or rectifier.
