Aftermarket Shift Light
I'm thinking of installing an Auto Meter Shift light. All the kits I've seen are for standard 4, 6, or 8 cylinder applications.
Anyway they can be utilized on a Rotary?

I think the 2 rotor wankel has the same ignition pulse frequency as a 4 cyl so if the shift light uses the tach signal it will work. The tech support dept. of the unit's manufacturer should be able to help. An electronics geek could also design a light to go on with the red line warning tone but it would not be adjustable for rpm.

I'm going to look at wiring diagrams on Sat and get some of the cluster wiring locked down for the tach cluster wire.

It would indeed hook up to the cluster feed for the tach.

I'm guessing a 4 cyl would put out 2 sparks per revolution, a 6 cyl 3 sparks, etc.
I don't know exactly how a tachometer reads the timing, I'm just wondering if this information is correct for my own educational purposes.
