Has anyone have an installation guide for the heated seats harness (audi a3 8v)..
I've bought this harness (picture 1) from the internet.. almost all wires are connected, except one wire (picture2)
I don't know where this wire must be connected (There are no numbers or anything on this wire)
Does anyone have more experience with this or maybe an installation guide?

You shouldn't be retrofitting without access and understanding of elsawin wiring diagrams.

I assume you know you need a replacement climate control panel?

I'm awaiting delivery of the Kufatec harness you have there. Did you find out where it was to go? Can't be far since it's so short.

Did you get any instructions from them at all? Thankfully I have the wiring diagrams from what I understand from Audi the original harness is 2 pieces not one which splits off in the direction of the seats.

Hello David,

I still don't know where that one wire goes to.. Also didn't get any instructions ( I didn't buy it from kufatec, what I regret now)..
I've heared from another expert you have to code after installation of the wires.
Hope you can post the kufatec instruction after your delivery?

You do need to code it. I did mine the other night in preparation for fitting the seats but the harness is on backorder from Kufatec so it'll be a few weeks before I get mine.
Check out the VCDS map to find your nearest vcds guy and it'll take 2 mins max to enable the option.

I think Kufatec also sents installation instruction by email if you have an ordernumber

Got my harness last night and no instructions either, did you resolve the problem of the location to terminate the lone wire?

Sorry to bring back such an old thread. I have just fitted Kufatec loom and coded with vag com. I still have no heated seats. The one thing that worries me a little is, I had no second wire in my kit. Is the reason my seats aren't working because I'm missing the wire ?

Any help would be very much appreciated.

Looks like a power wire.
In elsawin you can see 2 power wires from bcm to fusebox.
Fuse 31 is going to pin t73c on bcm (red/grey)
Fuse 42 is going to pin t73a pin 73 (red purple)

Do you find solution?
Can anyone upload the kufatec diagram?
I want to make retrofit and wiring diagram is important.
Thanks in advance
