I just swapped out my 4.3 V6 in my 2004 GMC sierra. I used a 5.3 from a 2003 Chevy Avalanche with the DBW pedal. Everything works except the cruise. Does anyone have any info on what is needed to make it work? I'm sure it involves something with the pigtail that went to the drive by cable on the V6, just not sure how to make it work.
