Brian,
I think it depended on your original application. I believe 4K is the more common, but 2K is doable, and then check that flag "output sped not from DRAC"
As far as the P/N switch: Since my C1500 was originally a 7747 ECM, it had a P/N switch on the end of the column, under the dash, inside the cab. When I still had the 7747 in there, I hooked up my laptop and when I unplugged the P/N switch entirely it showed as being in "Drive" all the time that way. (T-56 here BTW) I've left the P/N switch unplugged since swapping to the 7427.
