im looking into getting glow gauges, but i woul dlike my pickup to have a tach. the glow gauges would only be a faceplate correct? i would actually have to buy a seperate tach?

 

Yup.

 

well any idea of how i should do this? is there a cheap tach i can get seperate to go along with a glow gauge face plate that has the tach on it? i remember readying a post about someone putting a tach on there truck and it was mentioned there should be a cable to attach one already, so it should be a simply plug in job.
