Easy to make your original loom fit the b7 rears costing £0. If you get the b7 looms with your new lights. Cut the tail light off your b6 loom and then solder the 501 tail light from the b7 loom onto your b6 loom. Then all the holders fit into the b7 light fine apart from one which needs a 1 mm slit cut into the plastic on the light hole of the b7 light. Then all you need to do is either tape up the 2nd reverse and fog lights and tuck behind the light(I had it like this for 6 months) or cut the holders off and fit a resister (I have now done this) then you just nneedto code the top tail light out with vcds. Lights are expensive if your inpatient, I looked on ebay every day for 3 months and ended up paying £20 for one light and loom and £25 for the other light and loom.If I knew what wires went where I would lol
