The dilemma, new funky rear 03 lights with old non funky 00 wiring harness.
New harnesses from MrT £45
The issue is that 3 of the lights are push fit and will move to the new light fitting, the indicators however are not, they are bayonet and will not fit.
Some people have used a Dremel on the light fitting but this will damage the fitting, so this is what I did.
Buy an OLD rear light wiring harness for £5.
1)Go and buy some amber push fit bulbs from Halfrauds!
2)Cut off 2 of the push fit lamp holders from the new harness with a decent tail.
Trim the smaller lugs off the light fittings with a stanley knife so only the 2 larger lugs remain

3) Cut off the 2 fat bayonet fittings from the harness on the car with a decent tail.
