System Check Tachometer harness?

Last year I purchased a boat with a 2005 Etec 90/65 Jet Model # E65JDPLSOS.  It has the tiller handle kit #5007125 and the tiller wiring harness #586934.  I would like to install the system check tachometer # 0176309.  Is this gauge compatible with the 2005 Etec? 

The tiller wiring harness has a 6 pin connector for system check at the tiller arm, but most of the System check tachs have the 8 pin.  The 6 pin appears to have the 4 tan warning light wires, gray tach wire, and black ground wire.  It appears that I need to capture the purple switched power somewhere.  Does Evinrude make a harness for this setup?

Re: System Check Tachometer harness?

You need to purchase a standard MWS boat wiring harness and it will connect inside the tiller arm and route it to the console where an 8-pin connector will plug into your SystemCheck tach and the 2-wire connector will plug into the warning horn. Your dealer should have those items in stock or can easily order them for you. The tiller kit instruction booklet shows how to install the optional MWS cable inside the tiller arm.
