Step 2: Remove and rewire!
Disassemble the knee plates (Beetle version, Golf/Jetta is similar)
Remove the fuse panel cover
Remove the Headlight switch by pushing in and turning the switch, then pulling the switch out
Remove the dimmer switch
Remove the cover plates on the hazard switch panel
Remove the four screws on the Hazard switch panel
Remove the six screws on the knee panel
Remove the knee panel
Remove the four screws on the Metal knee panel
Remove the metal knee panel exposing the relay panel
Remove the two 10mm nuts holding on the relay panel
Remove the 175 relay (we're going to be using the socket for the 53 relay shortly)
Remove the insulation covering the firewall where the clutch pedal will go
Remove the plug where the clutch goes
Please reference your Bentley manual for actual pin-outs, and wire colors as these vary by year/model, also make sure to check for continuity on all items.
Connect Reverse lights
Cut the transmission range connector off of the wiring harness this is the connector on the back of the transmission near the ABS pump.
Use the Black/Green wire to one side of the reverse switch
Continuity check the Yellow/Blue or Grey/Red wire from the 175 relay socket to the matching color on the Transmission range switch wiring.
Cut this wire at the 175 socket
Cut the Black/Blue wire with enough wire to spare a butt connection later for the clutch cancel switch and connect side that leads into the harness to the yellow/blue or the grey/red wire in the previous steps. This is a standard butt connection that connects the reverse switch to the reverse lights. Heat shrink this connection
Connect the transmission range side of the Yellow/Blue or Grey/Red to the other side of the reverse switch. Heat shrink these connections
Connect Clutch Cancel Switch
Cut the brown wire at the 175 relay and connect it to the Grey or White clutch pedal switch (on the top bracket)
Connect the other wire from the switch to the Black/Blue wire you cut for the reverse lights in the above underlined and bold step.
Cut the Green/Black wire from the backside of the 175 socket (should be pin 5, or the one directly in the middle of the socket) and connect it to the blue or black clutch pedal switch (the bottom one)
Cut the Grey/Red (yellow/green on 2000+ vehicles, should be Pin 9)
Check for continuity on the Grey/Red or Yellow/Green wires in the TCU connector to the grey/red or yellow/green on the 175 socket
Connect the Grey/Red or Yellow/Green wire on the 175 socket to the other side of the blue or black clutch pedal switch
Remove the TCU from the car
Pull apart the TCU connector
Disconnect the ECU harness and pull apart the large connector
There will be a yellow/red wire that has continuity with pin 19 in the ECU large connector. Cut this wire at the TCU
Connect the Yellow/Red wire in the TCU to the Grey/Red or Yellow/Green wire in the TCU.
Move the wire from ECU pin 19 to pin 66 (98 and 99 beetles are pin 44 so verify the connector pin in your bentley before doing this).
Heat shrink the Butt connectors.
Wrap the unused connectors in Gaffers tape or other harness tape. (You may also cut the unused harness out of the loom).
Reassemble the relay panel
Place a 53 relay into the modified socket.
You now can start the car! (almost!).
