Hi - just fitting the rear lights an haven't
got a wiring diagram to tell me which of the rear light contacts is supply to brake ight, and which is supply to rear marker. Any ideas?
Failiing that, is it the brake light which is supposed to be brightest? Thanks

Brake light is 21W, side light is 5W - Use a small 12v battery to establish which is which...

Brake lights are the brightest....
You definately want the brake light system to work- people have a nasty habit of driving up the chuff of Se7ens because they think they're bigger (therefore further away) then they actually are.... If your brake lights then don't work it's even worse....
I even went as fitting as high level brake light- I worry that because so many cars have them people won't be looking to the periphery of the car for signs of braking....

Done, thanks. Now fitting the boot lid - with the fuel filler cap - then hopefully Vroom.
