I am installing a Racepak G2X unit in my 86 911. For the tach connection, how should I connect.....between the DME and Tach or off of the coil? And which wires should I connect to??

By the way I have the MSD unit that cleans the tach signal to make it suitable for the G2x. I originally had this system on my formula ford and kept it when I sold the ford.

Thanks in advance,
