I have been asked multiple time since doing my B7 rear light retrofit about how I did it without the kufatec loom. So Im doing a small guide for anyone else that wants to do the mod. I'm sure there are other ways of doing it without the kufatec loom but this is how I have done it
Items needed
B7 rear lights
B7 rear light looms
B6 rear light looms
Mini saw blade
Phillips screw driver
Soldering iron
Solder
Shrink wrap
Resistor (optional)
VCDS (VAG-COM)
1) remove the B6 rear lights from the car and unclip the loom from the car
2) Remove the B6 looms from the B6 clusters
3) Fit the B6 looms into the B7 clusters, you will see that every blub holder fits apart from the top brake light and the tail light (in the photo the top brake light is already fitted)
4) Cut the large bulb holder off the B6 loom so you are left with three wires
5) Cut the small tail light bulb holder off the B7 loom
6) Now solder the two brown wires from the B6 loom together (the ones that were attached to the large tail light bulb holder that you cut off)
7) Now slide a bit of shirk wrap over the brown wires (do not heat it yet, leave it loose)
8) Solder the single brown wire from the B7 501 tail light bulb holder onto the two brown wires of the B6 loom
9) Side some shrink wrap over one of the grey remaining wires and solder the remaining grey and black wire from the B6 loom onto the grey and red wire from the B7 501 bulb holder and then heat the shrink wrap
10) To make the B6 top brake light holder fit the B7 cluster all you have to do it cut a small 2/3mm slit into the B7 cluster like in the photo (I used a butter knife and it worked perfectly)
11) Fit your B6 brake light bulb holder into the B7 cluster
12) Fit your newly soldered B7 tail light into the B7 cluster and you should end up with this, nice, neat and almost factory looking
13) Your O/S cluster will have a redundant reverse light bulb as the B7 on has one reverse light and the B6 has two. Your options are either just tuck the redundant bulb behind the bumper or cut the bulb from the loom and fit a resistor to cancel out any bulb out warning from the dash
14) fit the lights to the car
15) Code the top tail light out using VCDS to make the lights look correct.
(I may not be 100% correct on this as it was a long time ago I did it)
Right down any original values before changing them.
Go to
09-central electric
Adaption -10
in channel section go to channel 02 this should be the brightness of the upper tail light and hit read
It should show a percentage which I think is set to 25%, change the value to 0% and hit test then save.
That should be it. Please correct me if I'm wrong on this. I will try and confirm the coding on my car on Tuesday.
Enjoy
