This will be as simple as wiring a 1500 for a 4L80 swap. The connector at the transmission will get repinned and you'll have to add the front VSS. Other than that, just plug in the appropriate 4L80E PCM and you'll be good to go. Are they both 4wd? If not, IIRC the 4wd just uses an extension harness to reach the t-case. Easy peasy.
