I am putting a 920 header on an 8820 without DAM, only height control. Does anyone know the part number to the adapter to hook the rectangle 3 blade plug on combine to the 16 pin plug on the header? Dealer is trying to find it but not having any luck.
 
Here is 3 blade to newer 9 pin 220 header discussion. Don"t know if this will help or not.
I think they made a backwards compatible harness, 3 blade on the head, DAM on the combine but you want the reverse.

You can't use a DAM head on a non DAM machine. You can go the other way but not the way you want. Just go to a bone yard and buy the DAM harness. It is the same for JD 6620,7720, and 8820. You need the control switch for the cab. The control box that goes buy the hydraulic reservoir. Then the harness from the head to the control box and to the control switch.

It does not take long to install. I used to do it in under two hours after I had done several. They DAM is worth having it works much more reliable than the old switch type.
