Programming BCM with VXDIAG and GM Subscription for Heated and Cooled Seats

[73TA]

I have 2013 PPV Tahoe. I plan on replacing the interior out of a 2010 Tahoe LTZ. I acquired everything from the donor vehicle from the inside except the instrument cluster. I have all the wiring harnesses, door panel switches (basically the complete interior) for the the heated and cooled seats, etc.
I could probably replace the HVAC system at the same time since I will have it all out anyway and convert it to the digital dual zone system.

So the question is this, would it be easier to use the BCM from the donor vehicle and just reprogram the vin and probably tweak a few things to it using this https://www.amazon.com/VXDIAG-Tech2...074365Q6H/ref=cm_cr_arp_d_product_top?ie=UTF8

Or just try to reprogram everything (remote start, interior lights, seats, airbags, etc.) to the original BCM using the same software listed above?

If the donor vehicle BCM doesn't need programming other than VIN, that maybe easier.

If you are getting VXdiag and programming anyways.. except someone may want the PPV BCM since not everyone likes auto headlights etc. I had changes made to my non-PPV BCM to turn auto locks and lights off. Might keep the original as a spare.

Regarding the climate control swap, please keep us posted. I am attempting to do the opposite and convert my auto to manual. (Already ordered the controls.. not sure if I need to change wiring) I have seen a post where someone added 6 wires, a couple sensors and a couple pins to convert from manual to auto.. When connecting to the Tech2, it asks manual or auto hvac, so I am guessing that information is not programmed anywhere..

Mike, how did this conversion work out? Sorry, I never saw the post.

Too bad he hasn't been on here since Jan 2022. Hopefully he gets a notification about it.

Whoops! I didn't see the original post date!

But I would like to add..

The J2 plug is different (won't plug in) between auto and manual (supposed to be blue in the manual, the auto j2 plug is black) Briefly looking at wiring diagrams, I'm not convinced the three plugs that will plug (J1, J3, J4)in are wired correctly anyhow..

Will have to take a deeper look at it sometime in the future...
