GM wireing harness

[RD400HP]

Does GM use the same harness for each one of its models. In my case I'm thinking about buying a 08 Chevy Express cargo van with very few options I have a 03 Express cargo van that I had to park that is pretty well loaded options wise would I be able to take the options off my 03 and use them on the other Express or is the harness totally different. I watched a Utube video about putting cruise on a van that didn't have cruise and all's they did was change the control stick and all the wires he needed for the cruise was in the harness already, thanks for any info that you can provide.

I doubt it. You could call dealership and get part numbers for the two, even if no longer available. Compare the part numbers.

If it's anything like the 6.5 you can ad cruise by changing the multifunction stalk as it's controlled by the PCM. Also my 99 had some extra wiring but I wouldn't count on it having it

Thanks guys I was just wondering since I saw the Utube Video about the cruise. My Express has heated power mirrors I wouldn't mind using if it was plug & play.

Be easy to tell , pull off that triangle piece of plastic , it should be right there.
