How to hook up a tac???

My dart has no tac. But I am trying to tune it up with my good old sears tun up tac. And I would like to add one of the vintage looking sun tac's at sum point. I am embraced to confess that I have had GM HEI ignitions for way to long, and have no clue how to hook up the the mopar electronic ignition. My last mopar was in high school, and well my memory is not what it once was. Thanks for any help!!
