I've been running an analog Autometer tach on the Sprite and decided I'd like to add one of Summit's digital tach/shift lights. I incorrectly remembered the analog tach having an additional output pin on the back. Any idea if I can I run both tachs off of the same wire coming from the negative side of the coil?

Shouldn't be an issue.

Yeah, should not be a problem. If for some reason it is, a diode should take care of it.

Cheers.

A driver with 2 tachs never knows what the RP is :rofl:

I think 3 plus a hot spare would be good.

Thanks guys - I'll give it a shot.

I actually didn't want two tachs; just one analog tach and a shift light. I couldn't find just a shift light that I liked, was cheap enough, and was small enough to fit so tach/shift light it is.
