    Pin 121 has this color. But there are two cables with this color. Second at Pin 90. Both from throttle actuator. Maybe swapped?

    At attachment wiring diagram. But it is in german, because I am a german. :-)

    @ brobble Hi there, thank you kindly for your help, cannot understand your diagram though, english only.
    i have the correct throttle actuator wires, this single wire just cannot see where it connects to opened the whole wirring
    harness but cannot see it cut from anywhere.

    But the yellow circled pin is pin 121? So it is from throttle actuator. I took a look again. I found 4 cables with same color (purple/white), which are connected to ecu:

    - 121, goes to throttle actuator Pin 5 (1.0 mm2)
    - 90, goes to throttle actuator Pin 1 (0.35 mm2)
    - 115, goes to egr valve Pin 5 (1.0 mm2)
    - 80, goes to fuel pump relais, over connector box under the front wiper (T6/2) (0.35 mm2)

    Good luck.

    The circled pin is 116. If this cable comes from EGR Valve, the cable must be pinned into 115. But in 115 you have blue/yellow cable. I cant find a blue/yellow cable, which directly goes to ecu.

    @brobble, thanks for your help, sorry i did not mention that this is a import golf 4 (think from japan) the wirring loom in the import
    version and our golf 4 in south africa is different. the original ecu plug was damaged and i used another one from our local golf 4 , thats
    why the wire colour difference.

    i need to know the pinout for the temperature switch and the map controlled thermostat please.

    many thanks
