I suggest doing this all before installing the clutch pedal, it is a tight spot to work in.
1. REMOVE Park Neutral Relay 175
2. Pull out the socket for the 175 to get access to the wires CRUISE CONTROL HOOKUP portion
3. Cut the GREEN/BLACK wire (pin #5) close to the 175 socket and connect to the blue or black clutch pedal switch (closest to the driver seat)
4. Cut the GREY/RED (YELLOW/GREEN on post 99.5 Mk4’s) wire (pin #9) close to the 175 socket and connect to the other wire on the same blue or black clutch pedal switch
5. Remove the TCU and disconnect the plugs from the ECU
6. Find (continuity check…) and CUT the same GREY/RED (YELLOW/GREEN on post 99.5 Mk4’s) wire at the TCU connector.
6a. Find a YELLOW/RED wire on the TCU connector that also has continuity with ECU pin #19 YELLOW/RED wire. Cut it at the TCU side and connect it to the YELLOW/GREEN wire. (1st check for unwanted continuity with any ECU pins)
7. Remove ECU pin #19 and pin #66 and put the pin #19 with YELLOW/RED wire attached into empty hole #66 (98 and 99 beetle it is pin #46 so please check before you throw 12v to the wrong pin)
