Re: Tach adaptor question

I am hoping once again you guys can straighten me out!!! I attached the instructions. Where do I connect this thing? I get the switched 12v side, its the other wire. Does it go between the distributer and the coil? Or after the coil?

THANKS!!!

Honestly I am not sure why you would need a tach adapter. A tach just hooks up like this.
The green wire is the "tach" signal which also goes to the negative side of the coil. Brown wire goes to ground and red wire to ignition hot.
It shouldn't matter what kind of coil you have, and it shouldn't even touch your dizzy. Atleast thats my thinking of it. Hope it helps
