Does anyone have the wiring diagrams from a 94 3500, specifically the cruise control? 

I Cab & LS swapped my truck and I want to continue using the oem dbc cruise control. I have the original steering column in the truck and that section of the harness, but everything else has been removed and will be replaced with a new non-oem harness. 

The truck had a 5.7/4L80e and now it’s got a 2001 6.0/4L80e I’m hoping the vss signal will still work for the older cruise controller.

Welcome to the forum Dr Frankenstein! What year cab did you use? A newer cab will probably have a BCM where the cruise on the 94 went through the ECM

I used a 55 cab and a stand-alone LS swap. So no bcm.
