6N - fitting mk5 lights (update with pics)
Posted: Sat Dec 04, 2004 12:58 pm
This should have been here a long time ago, written by Speedlaw and slightly modded by me. Found some pics now... 
To get them completely flush with the boot lid, you need to drill out the middle hole behind the lights. That's right, it means drilling into the metal of the car, so a big 15mm hole is created. This will allow the middle stud of the new lights to sink all the way into the body. After that, the lights may need some sanding down of their plastic edge, but you'll find out soon enough. Use a power sander if need be or a file, I found that the bottom of the clusters could use a bit of trimming, especially on the right side.
The bigger hole
The trimming process (left is done, right is not!)
The bigger hole will render the middle screw useless unless you get some penny washers for the inside of the car. then you can tighten it up against the washers as normal.
With the mk5 bulb holders (which you WILL need) they are the same left and right - mk4 ones were reflected. Also, the indicator is in a different place on the lights so this needs to be sorted.
left side: you need to switch numbers one and two around. That's it.
LHS wiring (IGNORE THE EXTRA CONNECTOR ON THE RIGHT)
right side: slice off the two lugs on the plug that goes into the lightbulb holder. That allows it to be fitted the wrong way round to get round the difference in symmetry between mk4 and mk5. This is a good way to do it because the fog light still gets the thick wire.
After that, switch numbers 4 and 5, which should be Green/Grey and Brown ON SOME MODELS. So turn the plug around, and switch the wires. The wires you need to change (ONCE IT'S UPSIDE DOWN) should be the top two of the connector like you did on the LHS - you're basically swapping where the indicator and brake lights are (IIRC).
RHS wiring (IGNORE THE EXTRA CONNECTOR ON THE LEFT) with the flattened lugs
If you're fitting LHD lights like mine, swap the clear foglight bulb in the RHS cluster for a red one - UK legislation says the fog light must be on the RHS of the car to pass an MOT. Stick with the red reverse light (oh well) or apparently you can smash the red reflector from inside and pick out the pieces (
) but I'm not sure if this looks good.
The finished result, flat and bling!
