Right well heres a basic guide thats adapted from the
old site . Not as many pics as I'd like but will have to do just now!
Items needed= Mk2 ph2 rear lights complete with bulb holder and small screwdriver.
1) Remove the old tail lights and bulb holder by unscrewing them from inside the boot and unclipping them from the wiring plug.
2)With the wiring block lift the bit of plastic at the front (marked number 2)to access the wiring.
3) Swap the indivdual wires according to this diagram
4) Clip the new lenses onto the new bulb holder and push the assembly onto the adapted wiring block.
5) Refit new lights and screw them back on, and test.
If anyone has step by step pics or anything to add please fell free to as its over 2 years since I did this mod so memory maybe isnt spot on!
Cheers
John
