aftermarket TACH?

Hey guys, my stock tach is bad, it no longer works. I was wondering what any of you guys, who have used aftermarket tachs used and had luck with. What do I need to do?

I would troubleshoot why your tach doesn't work.

It gets its signal from the trailing coil I believe, check the wiring diagram for your year:
