A good friend helped me wire the OD when I installed in my 70. With a regular dizzy and coil you wire to the point side of the coil to make the engine lose power. Since I had a HEI he simply wired to the tach terminal - didn't have tach. I was sure it would fry the module but it worked like a champ for several years.

I am not recommending anyone do this - but it worked in my case.

Maybe and HEI expert could explain/verify.
