90-93 DIYPNP fab9 coils tach
 

hey guys,
trying to get my tach working with fab9 coils.
currently have pins 4 & 5 on the igniter harness tied together and have tach jumped to 2I.
no tach movement.

am I missing something? does tachout need to connect to S4 then jumped to 2I?

any help would be greatly appreciated. thank you.
