Description:
For that rare fellow who would like to add factory heated seats. It can be done. First you must acquire the heated seats. My car is a 2007 GT3. I was able to, when a Rennlist member put his nearly new ones up for sale on that forum. He was replacing them with the GT2 seats in his 2010 GT3.
Next you need the HVAC Climate Control Unit. Part # 997 653 111 14 (Note the last digit can be 1,2,3,or 4. 4 was the most recent update.) These can be found used on ebay and other internet sites, as well as new from a dealer. I used Sunset Porsche.

I swapped out the seats and the control unit myself. Directions for those steps can be found on other posts. Planet 9 has a good article on PCM install that shows the Climate Control Unit removal.
The wiring harness for the heated seats connects exactly like my non heated seats did. The only problem: no wire was present to connect seat heaters to Climate Control Unit . My pals at Harper Porsche, the Knoxville dealership came through with the solution. A wire was ran directly from the Climate Control Unit to the seats, under the carpet of course. The final challenge was the wire connection. Jason, a Porsche Service Tech did a lot of research. This is the Gem of this Mod. Those connectors are a BMW part. Jason tracked them down and eventually acquired some. 30 cents each. Originally used in an older M3. (This has to be an abomination of some kind!) Hardwiring is an option but he was reluctant to go this way.
I picked up the car today. The outside temp was 38 degrees. The heated seats worked great! Toasty buns.

Have you installed this Product or Mod?: Planned
Please

provide more detail on the connection. From the Cayman wiirng diagrams the supply voltage for the heated seats comes fromthe central computer network control box and not from the

a/c dash control unit. thanks

Pros: ability to add heaters
Cons:

Information received for the tech who did the work.





Parts you'll need:

A/C control unit with heated seats control.

2 eye terminals for seat ground wires

2 foot of 18 gauge wire

20 foot of 14 gauge wire

4 terminals for vehicle electrical control unit connectors BMW part# 61.13.6.913.612 (get 8 just in case)

4 terminals for seat connectors BMW part# 61.13.8.364.848 ( get 8 just in case)



A/C control unit must be programmed by a Porsche dealer. Some module coding may have to be changed also.

The vehicle electrical control unit is located under the left dash area on top of the relay carrier, you'll have to remove the fuse carrier cover and relay carrier to get to the control unit. It's not necessary to remove the control unit, just remove the electrical connectors from the control unit.

Run a 14 gauge wire from Black connector housing pin 1 to passenger seat connector housing pin 8.

Run a 14 gauge wire from Grey connector housing pin 25 to driver seat connector connector housing pin 8.

Run a 14 gauge wire from passenger seat connector housing pin 13 to ground.

Run a 14 gauge wire from driver seat connector housing pin 13 to ground.

Run a small gauge wire from electrical control unit Black housing pin 2 AND Grey housing pin 26 and splice both wires into Grey housing pin 23 wire(red with black stripe).

P.S get the wiring done first before letting dealer to program the AC control unit and change coding in other modules; because you may set the airbag light on while working on the seat connectors, so that they can clear the airbag light at the same visit without additional charge.
