Control Box Wires Question

[imstillatwork]

Engine: 1981 70HP<br /><br />I was out cleaning up the boat, pulling out old wiring, installing new batter cables, etc..<br /><br />I noticed on the control box there are three wires coming out of it along with the throttle, shifter and main harness. Purple, grey and black.<br /><br />What are they and why would someone cut them off at the box?<br /><br />The electric choke, ignition, overheat alarm all work well, I don't know what the other three wires are though...<br /><br />Thanks!<br /><br />Kevin

I don't have a schematic for an 81 but I would guess they are your tach leads. Black is ground, purple 12v and gray the sensor lead.
