Anybody remember Craig Powerplay?

A while back I put an ad on Kijiji looking for an 8 track player. Specifically the one that can be removed from its mount and alternatively replaced by a cassette player of the same model. Well I just received my player. :D It is in very good condition. Now to find the matching cassette player! I had forgotten how heavy they are! It weighs 3 pounds! This just to show the younger generation what we had. This was likely the first attempt at theft prevention, much like removable CD faces today.
found this old thread. I just aquired a Craig Powerplay like this one. Do you possibly know the correct wiring diagram? I have it working on the test bench but want to make sure I've got it right. Thanks!
