Possible to add heated/cooled OEM seats?

[Gcgordon1216]

I’ve researched the web all night Harveyfamily seems to have the most information I’ve found, I’m attempting to install 2015 up GMC Denali leather heated and cooling seats into my 05 H2 Hummer SUT, if at all possible please provide you assistance knowledge and experiences on wiring these seats up of course my attempt is not your simple swap maybe requiring a BCM flash it’s probably best to just send me an email [email protected] Thsnks

I am still figuring out the wiring to set this up.  At this time I have no advise to add.

Recently started looking into this type of swap for my 2018 LTZ. I found a plug and play harness from the Harness Dr. Claiming to allow for both heating and cooling!! Link below:

Anyone know if it is possible to modify heated leather seats with memory that they gain the cooled function? My leather seat cushions and the seatcover itself needs replacement because of wear and tear. So I thought to buy vented seat covers and retrofit all the stuff needed. Anyone know what parts differ or if it's even possible.
