6 Volt Tach connection and built in coil

[fortyonerag]

My 41 convert has a stock distributor with built in coil. Stock V8 in all respects

I recently came across a Sun 6 Volt Tach and EB-1A Transmitter for 6 Volt 8 Cyl operation. I'm not wedded to it, but it would be nice to run it.

The wiring schematics I have seen show connection to the distributor side of the coil. Can this be achieved with a built in coil or do I need to run a separate coil?

Apols if this has been covered before - I did a search but came up empty handed.
