Although mine came without the CPD Interface Module, the checklist indicates it should have come with one. It lists:
- 8583446-CPD Interface Module (8583469) w/ custom cable and instruction sheet
Edited to add: mine is newer, with the LED alleys and takedowns. I have the bag from the CPD Interface Module. The part number on the bag is 8583446B-CPD. This leads me to believe there also exists an earlier model 8583446A-CPD as well.
