Well Guys, I am almost ready to get my truck back from its recent conversion and I may have another snag. I have had my wiring guy also make my 4x4 wiring harness. (I swapped in the 2004 transfercase along with the rest of the 2004 drivetrain.)

Here is the trouble. The harness that I finally received after a two month wait has connectors for Speed sensors for the front and rear driveshafts but my particular T-case had those speed sensor holes plugged up at the factory. They are not there. I am worried that the harness was made for the wrong t-case as they used a wiring diagram for a 2004 K truck. Is there another wiring diagram for my application that someone could share with me? My T-case appears to be the NP1 according to a print out that I have

The donor was a 2004 K2500 HD built on Jan 22, 2004 Vin is 1GCHK29U94E253034.

Does anyone know why GM plugged the holes on this T-case and whether my harness will work minus speed sensors or what I need to do?

Many , Many thanks!
