I have an '89 40hp ELPTO Mercury. Is there anywhere on the net, that describes the control wiring (schematic or equivalent?). The boat has the standard remote quicksilver controls. <br /><br />At the motor-end of the wiring connector, there are four wires that appear as loose connections separate from the multi-pin connector. Two of them are in use, but the two others are not connected to anything on the motor. What could those two 'extra' wires be for?<br /><br />My boat does not yet have a tach. Do I need to run new wires from the engine for that, or are there wires in the quicksilver controls? Perhaps if I can see a typical wiring diagram that would help.<br /><br />I do not have a service manual yet, and no owner's user manual for this setup. I will be ordering a service manual, but fear that it will not discuss the controls/wiring in detail.<br /><br />Any help is appreciated.
