What colur wire is the stop light?

[mun802]

On my SLK R170 the tail lamp has a plug with wires numbered 1-6 and colured accordingly:-
1=Brown presumably earth?
2=Grey/Black
3=Black/White
4=Red/Black
5=Yellow Grey
I'm trying to find out whic one is for the Stop light and which one is for reverse as I'm wiring up the parking sensors.
Thaks V much for any help.

Just use a meter on the metal ribbon in the light unit to deduce which connector feeds what.

Would if I had one.

Make one. Get someone to step on brake while you test. Then put in reverse and test again.

Should be the Black/Red wire (black should be the main colour). Also the 5th should be grey/yellow. (You must be talking about the left light assembly for a RHD car?)
