I am the new owner of a 135 Mariner long shaft. I purchased with no controls and was wondering about buying a key switch and wiring harness from a liquidator. Merc part number is this...84-816626A20. My question is will it operate this motor and its two warning horns and a tach???<br />Thanks...by the way this is my first merc/mariner It looks like a good one, is it?? 2.0 liter block v6 very clean with strong compresion and little hours.
