Schematic for heated seats?
My Silverado has a separate button just for heating my spine, and with my worn out spine it is my favorite option ever.. I would like to disconnect the bun warmer and just use the spine warmer on my Stingray. I'm thinking I can disconnect the bun warmer heat element, ck the resistance of the heating element, and replace it with an appropriate resistor, to fool the BCM that everything is ok there.
Can anyone help me to find a schematic for a 24' Stingray LT2 or 3?
Thanks.
Please spare the opinions of this need and I don't want to sit on a pad to insulate from the bun warmer. Thanks.

I can't help you with your diagram, but can point you to a place that might.

OK, if someone can verify my ohm's law math using an educated guess of the heating element amp draw to figure resistance.
15a fused protection for both bun and spine warmer, so 7.5a max each so perhaps 5.0a draw nominal for each element (guestimate)
12v system
12v/5a=2.4 ohms
So a 2 to 2.4 ohm resistor between (2077) BR/VT and (2078) BR/BK should keep bcm happy.
What do ya think? anyone?

So, you're thinkin' you need a dummy load there to prevent a DTC then? Math looks ok but why not just measure the resistance of the heating element. And....I think you will need a heavy duty resistor - it is going to get HOT I think. You will be drawing (v^2)/R = 144/2.4= 60 watts. Alternate calculation I*V= 5*12= 60 watts. Like a 60 watt light bulb, its going to get hot.

Hmmm, Heat......I'm hoping It won't throw a code(visible on dash) if I simply pull a pin out, Like the BR/VT.
Thanks for the input Andy. Now I wonder about the thermistor and how it comes to play.

Yes, the thermistor seams to be more a part of the fan circuit. The symbol next to the element is the thermistor.
I can feel a big connector in the rear of the seat, I'll have unbolt the seat for sure, I can get my fat head and one hand or two hands and no head between the fire wall and seat... work in progress.

Anyway, here is a clip of the whatchamcallit, and also a clip of the seat fan circuits.

I've never seen a relay on paper like that, normally it is 4 or 5 prong, 2 little amp solenoid connecting two big amp wires and maybe a signal.
I look at that symbol as a fan, but we have a separate drawing for that system. I looked around and couldn't find that symbol. Head scratcher. My old abused spine needs heat. Spine heater in the silverado is brilliant.
