What is this connector for?

[henkkeumus]

Hi,

I've bought some A3 8P S-Line seats from a car graveyard.
The seats include seat heating and retrofitted those aswell in my A3.

But my seats have 1 connector left that's not plugged in, obviously because my car didn't came with that function. But what is this connector for?

My thought was it is for the "detection sensor" so it detects somebody is sitting on the chair and then the dash can beep your ears of you need to plug in your seatbelt .

Could it be for the rear footwell lights?

Nah, I already have those fitted in an aftermarket solution.

And 4 cables are going into that connector, I assume a footlight only needs a power and earth to work.

Is it the connector that links the back part of the heated seats to the base where the supply comes in?

Could be the seat airbag?

Nah mate, I've retrofitted the heated seats in my A3, this is the only connector that's left (both sides).
Heated bottom and back work with the big black plug.

Could be the seat airbag?

Airbags go with the yellow connector.
Should be kinda dodgy if they made 2 connectors for 2 airbags, that's creating like more points of failure in case of a crash

Ah I see there's a picture, bloomin work blanks out the pics and limits your access to some sites. If i'd known there was a picture that would have made all the difference, let me see......... nah still don't know.

How’s about the internal alarm switch cancel in the B post?

Mmmh, why would that be on my seat?
It's also only on the passenger seat and got only 3 wires attached, wich I assume is; ground, live, CAN.

After some research and talking to the mechanic at Audi (was there for some connectors) they could tell me it's for the sensor in the passenger seat. It's a "detection" sensor just as I thought. It will detect if anything heavy is on the seat and when the seatbelt is not clicked in it will beep the living hell out of you
