This may be the wrong place for this but i didnt see a section that really fit the question any better than this one.

I was wondering what wire on the coil to run a tach lead to? I bought a tach tonight finally but Ive never hooked one up on the square coil type before. I dont have a wiring book for my truck either.

Thanks.
