Re: what color is the tach wire ..93 force 90 hp
Hmmm. <br />Well, then something is messed up with my manuals.<br /><br />Yes Realgun, on your 1988 85hp Prestolite ignition, the wire is purple, from the rectifier to the harness to the helm.<br /><br />bobrock, This is a 1993 90hp with the Thunderbolt ignition, right?<br />My manuals seloc, Clymer, and OEM, show all 4 wires from the trigger going into the switchbox, brown; white; violet; white/black. My motor is set up this way.<br /><br />Like I said above, it may be purple or grey at the helm end of the wiring harness, but should be grey on the engine, and coming from the rectifier.
