I want a tach for my car and I saw one I liked at NAPA today for about $40 and I'm wondering could I put it in myself or would I be better off paying someone else to do it. What all does it take, where do the wires go to? Any help is appreciated, as always!

I've come to realize that I'm gonna have this car till it pukes for good, b/c I'll never be able to bring myself to sell it.

 

i'm not sure what type of distributor/coil you have... but in a conventional one like mine, contact point/external coil, i hooked up the positive lead from the tach to the ignition terminal of the coil, and the negative lead to the negative terminal of the coil, it's that simple man... the tach gets the pulses from the negative terminal i think...

 

Yup! For wire colors & location, you want to splice the tach signal wire into the black/white wire (terminal "A") on the gray connector...

On my Sunpro tach, they just needed the tach signal wire to go the coil; they said to attach the tach's ground wire near the battery. I guess tach's are different in that way, so check your instructions!
