Question about Mercedes-Benz CLK
Not sure where you live in the world.
I am in Canada and your specific model is not listed in my manual.
I looked up the diagram under a CLK 350, I hope it is similar.
The system uses multiplex wiring, a signal is sent from one module to another eliminating the need for a bunch of wires to operate everything in the rear.
To find the wire color you need you may need to go directly to the bulb in the tailight assembly and find the proper wire.
On the CLK350 model the wires are Gray/Yellow to the right side and gray/blue to the left.
There is a module in the trunk that these wires lead to. It is a positive signal.
I hope this helps you with your installation. Thank you for using FixYa.
