Is Chris from Whites Auto?

I can vouch, you guys definitely did figure everything out on those cars lol

Yea, Chris is White Auto. As someone else stated his handle is always GTPrix

I'm not 100% the bcm don't have to correct info already stored. Sig from switches goes through BCM to seat controller to fan or heater.
It's a low data sig. I need to see if controller is installed.
Should be a small box in front on the seat. Cars inFL, I'm not. Some go look. Lol

it would be awesome if the BCM was programmed, it would be very odd though if it was and outside the norm for GM.

Are the NTC circuits referenced thermistors? If so, I assume this connector is between the seat and the seat controller itself.

I'm unsure. I will pull all the info when home, some time mid next week.
My wife went out and said she does see a small black box in front of both seats... Heater/vent module!
So, the seats have the heaters, fans , harness and modules. It comes down to the controls and BCM.

I assume you also mean the missing wiring that goes from the seats to the BCM as well, correct?

Yes, I believe so as the 2SS chassis wiring harness connector (male pins) definitely has more connections than our 1SS 1LE's do (ref. previous posts/pics).

That's the easy part. Adding wires and moving wires is nothing but pin out to pin out comparison. Memory seats add a lot of pins from my quick look.
I believe there is 7 different BCM based on options. What does that do to the dual ac controls? If the BCM has the heat/vent info, it's just running wires. This is not a quick process. But I am 100% confidant we can figure it out. The question is at what cost and how simple. So far I have $300 into it. I don't see much more needed unless the BCM becomes an issue. A BCM from a 2ss without memory would be cool to test also.
My biggest enemy is lack of time right now.
I decided against adding a control board. Far more difficult.

[Summit1le1ss]

Got board, so used hotel comp... Check it out.
Pins are not there on harness side as suspected.
11 wires to add.

The BCM is why I keep saying is going to be the hold up, you cant take a BCM from a 2SS car and put it into your 1SS car. They are VIN tied and it will fail the calibration check and wont work. The BCM in your car with your VIN programmed in it will have to have its calibration modified to turn on the seat features.

Back in 2014 when GM went with the Global system they got rid of the backdoor that allowed people to find a VIN from a vehicle that had the features they wanted and then to walk into a dealer and have the dealer flash the feature from that VIN into their vehicle to activate the feature.

I have worked with the chief engineer over the entire GM truck division for almost 3 years now, had engineers flown out to my house and the dealership several times. Been in position to be able to ask for favors and even had beta software installed in my truck years before anyone else has. The current way GM does it now isn't like it used to be. I have even suggested to the engineer to get GM back on board and to allow people who want to add the options back into their cars at their expense to get GM to allow the BCM to be recalibrated by GM and still couldn't get a buy in from them.

It really sucks, the aftermarket industry on the domestics is behind compared to the Germans. On my wifes Audi SQ5 I have a BT OBDII adapter and a software program on my phone. I can in and change all sorts of functions in her BCM in minutes, no issues at all. Audi doesn't even care about it.

Just from reading the stuff Chris has posted up over the last 10 years I know he worked from GM in some capacity which is why he knows the coding for the BCM, he is also the only person I know of that can access and program a GM BCM, and I have been on GM boards since around the time of 2001.

Believe me, I am behind you and I would love for this to work and for it to be a less than $500 modification, I would love for it to be an OEM update as well but I see possible further issues with having to change out to the 2SS HVAC controller (possible dual zone mode issues because of the missing sensors), adding wiring into the car now from the seats all the way up to the BCM, and now needing to get the BCM programmed.

Thanks for busting my bubble! Lol.
I admit GM BCM programming I know little, to nothing about. Ford is easy.
I thought about doing hvac module also if needed. The dual has a different Evap housing, one extra temp sensor and one additional harness for that sensor. plus the difference in controls. There is no options listed for dual Vs single other than that harness from the mod to the sensor to the Evap housing that controls the blend doors. Even the pin out's are the same.?? GM is odd.
I'm looking at the pin out of the bcm now and it has the data info across all models.
I need to look at the harness in person. Located driver side under the dash and see what is pre wired.
The hvac connector harness from controls to BCM is the same across models also, so it shows anyway. This makes me wonder if the plugs are their. Have to remove center console and AC controls to see.
The biggest issue I have is putting your vin in dosent pull up different info, as Ford does, so it's a lot of pages and looking at options.
Their is section about turning on and off options in the BCM for the 17 model year. I only glanced over it.
I know we can back up and just control using a CB and controller. But this was before knowing the seat module was also present. It handles not only the controls but the safety functions. This is important to me.
To get a sig to the seat module outside of the data circuit is possible also. Controlled by a separate switch. I'd rather do a factory install and exhaust those options first. I have about 100 pages printed out to look over later. 300 + miles from home and nothing else to do today... Lol. Just wish I had my car with me.

Well good luck, I know Chris is/was pretty active on the GM-trucks.com forum. You might try him over there and pick his brain some. He used to do a lot on his own, but now that he has partnered up with the company he is working with on the HMI updates.

I've contacted a few people. Zero response so far.
