W205 Towing Electrics??

[Bigglesw]

Hi All

I wonder if anyone here can help.

I am not able to find a wire in either light cluster that is driving the indicator.

I have an aftermarket full bypass kit which is working fine with the other lights, and I have no doubt will work fine with the indicators, just can find a wire controlling them.

Any help gratefully received.

Black/green and black/white iirc.
Can't remember which is left and which is right.

Solved. A multimeter is not sensitive enough to find the wire. With the protection of the bypass relay I simply dabbed the back of the plug until I found them.

The bypass relay is looking for tiny currents,
