Craig, when I lived in the Chicago area in the early '90s I went to the DuPage show every month. Dave was always there with a small table and some interesting oddball pieces. Probably more knowledge than the rest of us put together. In those days John Heck would take all my money!
I will look for my 322's later today but I know the ones with the "normal" trailing truck do not have individual wires, they have the harness.
