Hi,
there have been 2 different lockout switches: 4 and 6 connectors, but only 4 are used for cars without US exhaust regulation.
- black-yellow-red from fuse 5, 0.75 mm²
- purple-white to ignition switch, 2.5 mm²
- grey-yellow to backup/reversing light, 0.75 mm²
- purple to starter/clamp 50, 2.5 mm²
