BCM T73C Pin 15 Already Used

[Scott2]

I’m retrofitting heated seat controls in my T6.1
I have:
* Caravelle seats
* Kuratec wiring loom
* Control panel with heated seat buttons (T6.1)
* T6.1 module

Wiring done last night:
* Ground fitted
* SC55 fitted with 25A fuse

Opened up BCM C to find pin 15 already full.

I think I have two options electrically:
* Connector existing green purple and loom into pin 15
* Solder and wrap above and then enter pin 15 with one wire

Or should I use another empty pin?
Can I code this in VCDS? Should arrive tomorrow.

Thanks

Looks like the BCM Pin is a LIN data Bus.

So you will need to splice the new wire to the existing.

The BCM pins are hard wired so can't be changed, but you will need vcds to change the coding to enable new functions.

Since headlight and rain sensors are expensive in our country, I ordered this product from AliExpress. I need help from people who know about wiring
