Tach

Have a 69 superbee with a rally dash and tic toc tach.Can I use this tach with the mopar electronic ignition or do I need to change or convert it to something else?
Thanks,
Mike

I ran the tic toc with the MP setup and it worked fine. Tach wire still goes to coil- side.

What Pynzo said, that'll be the black/yellow wire on the pentastar ECU connector anywhere along it's length from the ECU to the coil neg where it's easiest for you to T into it
