Wiring diagram

36 is the Turn Signal Relay
34 is the Turn Signal Switch
Orange/Green is switched supply from key-switch (horn and brake light would also be affected if this was bad)
Green/White and Green/Red are the Circuits directly to the lamps themselves

As mentioned in previous post, shorting from LtGreen/Brown to either Green/White or Green/Red at the main harness connector will turn on the left or right side signals accordingly

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!
