Tachometer on Kohler Courage Pro SV840

I am wanting to add a tach on a Kohler Courage Pro SV840. I was going to order one but I had a couple of questions. I was wanting to go with a regular dial tach instead of the Tiny Tach. This going to be used on a hovercraft not a mower and I am using Speedhut's GPS speedometer and quad guage to measure fuel, volts, oil temperature and oil pressure. I wanted the dial simply for looks so it matches all the other gauges even though it is much more expensive.

The wiring instructions for this tach are at: http://www.speedhut.com/instructions...structions.pdf

A person from Speedhut said that you can take a wire from the flywheel and hook it up to the sensor wire on the tach. I am assuming he means the wire that goes to the voltage regulator. I was always under the impression that you were supposed to hook it up to ignition kill wire. Does anybody know what is the correct way to hook it up?

Also does anybody have any knowledge on the accuracy of dial gauges as opposed to Tiny Tachs?

The kill wire would be running from the coil sitting on the flywheel. That would carry the electrical pulse you need. Anything on the voltage regulator may be a little complicated if the pulse is coming from an alternator/generator.

I'm not familiar enough with the tach types you're describing to offer an opinion on the accuracy of either. If you have a single pulse per rev, though and all it has to do is show that in analogue, I wouldn't think accuracy would be a problem.

Thanks marbobj, I don't know why I didn't see that I feel dumb.
