    Basically, iv got the leather heated seats, the loom from kufatec and the climate control with the heated buttons, is there anything else i require for this installation? i just wanted to know if anyone else has retro fitted heated seats into an a3 and if they could provide me with some assistance? because i know that its not just a plug and play job.

    Surely you will need the heating elements for the seats??

    See above.

    I think thats all you need.
    the switches does all the controlling and the Kufatec loom makes it close to 100% plug and play.
    You just need to earth the loom and plug it in to a live with a fuse.

    right, that would explain the extra wires with the loom, theres three wires, im guessing, one must be permanent live, the other switch live and an earth? so could i earth it anywhere or is there a specific place?
    cheers

    Wire configuration:


    Red/ White - Constant Hot - Fusebox

    Wires (Gray) on the opposite needs to be connect to the climate control Connector D PIN 13, 14 Brown - Ground point A-column White - climate control connector D PIN 2 (if already used solder onto line) Blue/ Yellow - climate control connector C , PIN 10 Blue/ Red - climate control connector C, PIN 9 Gray with Yellow mark - climate control connector D, PIN 5 Gray with Red mark - climate control connector D, PIN 6

    All my wires. Are grey some have numbers on some don't im guessing the kufatec loom is made for left hand drive if this is the case I've connected the plugs the wrong way on seats

    I have the same problem, I've messaged kufatec asking for updated instructions and also made some educated guesses.

    I've tested the wires for continuity between the seat plugs and marked them for the drivers seat and passenger seat.
    The 2 grey wires that connect to one crimp I assume are ground for some kind of sensor or signal in the seat, I'm pretty sure these are white in the instructions.

    The two thicker grey wires are 12v, and I believe these are the grey with yellow mark and red mark, one for each seat.
    Which only leaves 2 skinny grey wires which must be the signal wires (blue/yellow and blue/red). the problem is knowing from their instructions which one goes to which seat. :-/

    Also I have the climate control unit in case that changes anything.

    cheers

    I just got a reply from Kuftec, apparently the wires have the colours written on them...I just checked and they don't have the colours written on them but the pins, and example T16d/5 so plug D pin5. hope this helps.

    Check the pins with a multimeter, my harness was cross wired for the heat sensors.

    We can convert them to work with your car. Have done it on a few cars now including my old a3 which had heated a5 seats in them.
    Pm me for prices

    I know this thread is a bit old, but I'll give it a try anyways as I am in the middle of retrofitting heated seats just now using the Kufatec loom.

    All my cables was grey as well, so purchased a multimeter to figure out where the cables goes to/from. All good and I am running the cables now.

    For the red/white cable which goes tot he fusebox - Am I correct that I should connect to "37 Heated Seats front"? If so, there is two holes, but one of them seems to fit with the plug (bottom one). Kufatec documentation just says "steady plus - fusebox". I can see that you guys says "Constant Hot" above, anyways, I just need to know where to plug in the red/white cable in the fusebox.

    Thanks
