Wiring diagram

Thanks. I work on mercedes and it's hard to perform a correct electrical test without a wiring diagram and a meter. I like to check diagram and then one test for result

I fixed it. It does have 4 wires to the switch. 2 orange on each side that comes from the relay. When bridging left orange to left turn signal wire they work. I sprayed good old wd40 in the switch and all works perfectly now. Yay for me!
