This is a simple mod and should only take 10-15 minuets to complete.
This modification will will only work if your Vectra hatch or saloon uses lights B and as side lights. Some only use light C as side lights so this mod wont work on those cars. Light B is also the brake light and will continue to work as before.
- Remove the black plug from the light unit and open up the pin cover.
- On the Off Side you need to swap Pin 2 with Pin 6
- Nearside move swap Pin 1 to Pin 5 (Empty Slot)
* Pin numbers are visible on the flap part of the black cover.
The Pins can be tricky to remove take extra care to to damage then pins and cable.
