Thank you
pin 6 is 12v i just run a wire with new connector as above to the switch and back into a joint for pin 6 to get power, you can run the wires through the drain for the A/C its easiest way its a pain to get the the abd module you need to remove battery and undo the fuel filter to get it out and up enough to get the cover off the connector budget a good few hours to do it properly you may need some coding to get the asr to turn off
In the Connector the fields A2 to A5 should be empty. For your orientation: Pin 1 and 25 are red, Pin 13 on the other end is brown and Pin 38 is not connected.
just get soldering iron and gently remove some of the insulation from pin 6 thats KL15 12v get a twisted pair of wires and run them both to the switch in the dash the switch is a momentary switch so check with multimeter the connections basically then you have a pair of wires one with the new pin you click into T4 and one soldered to pin 6 12v if you have the OEM part number dash switch then it will have 4 pins, one is earth one is 12V for lights i never bother with, the other 2 connect when you press the button down you want those 2 it doesnt matter which way you wire those 2 together as its just creating a connection to aplly 12v to deactivate the esp

Was probably a bit messy worded.
On the connector for ABS: pin4 and pin 6 to be connected.
Where should this be connected to the TC button?
And can I take 12v from another place than from pin 6 on ABS? For example from the start-stop button?

As I read from earlier in this thread, I can use pin4 from start-stop button to pin4 TC button instead of pulling cable to pin6 ABS connector.
So then I conclude that I connect pin4 from ABS connector to pin5 TC switch. Pin4 TC switch to pin4 start-stop switch. Is there more that needs to be connected in the TC switch?
Only -ve brown and +ve grey/blue for the switch illumination if required.

Does anyone have a flow diagram for the start / stop button?

On this diagram pin 4 abs to pin 5 TC button
My first retrofitted traction control switch deactivates ASR only

to actually work as a ESC deactivation switch

More details to follow soon
Any news here Robert?
I have switched from ASR OFF to ESC OFF

Have connected according to this self-made drawing. Everything works except for the light in the button when it is activated. Is there anyone who can give a tip on how I can make the button light up?
Traction Control Switch has only illumination light inside. According to ERWIN wiring diagram there is no indication light.
Why do you want your switch to indicate it if you are getting this via Instrument Cluster dedicated LED?
On a side note, HDA switch has indication light built in but even if this is wired in it still doesn't work.
