My understanding is with a 7060 in the early years they installed the reluctor at back of trans whether 2 or 4 wd and just plugged the rear speed sensor hole on 4wd and sent the transfer case output to b5 and b6. If it was 2wd the signal went to a drac and was then sent to b11. I think the signals are the same so probably could sent the tcase signal to a drac and as long as you weren't using 4wd the 7060 wouldn't know the difference.
