I have had a wire harness made for my 2004 K2500 HD Transfercase so that I could plug it into my truck along with the 6.0 and 4l80e. I have wire diagrams for a 2004 cheverolet chevy K silverado 4wd. The problem is that the wire harness was originally built for a the 1/2 ton shift control module rather than the heavy duty one. I am told that the only difference between the two in the speed sensors on the T case.

Is this True?[/b]
no, it is not true, the pin out on the transmission plug is different than the 60e tow wires swapped plus an
ISS is used on the 80e the 60e does not use an Input Shaft Speed (ISS) sensor
