Does anyone know how to wire and where to connect the rear fog light on a NX300? The new lamps I got replace the OEM reflectors installed but not sure where to connect the wires as I don't have the wiring diagram. Need this to take along the car in Europe from USA.

 

You'll have to get a TIS subscription, you can buy it for 48 hours. When i did my 7 way hitch plug i didn't see any other wires near the tail light harnesses. Maybe the USA lights don't use all of the wires in the harness, but i'm not sure off the top of my head. TIS would be your best bet, or you can try a test light or multimeter and start probing pins while someone turns the fog lights on and off. You can get to the tail light harness without removing any panels in the trunk, just need to remove the small square carpeted covers on each side.

 

Can you post pictures of the new taillights for us please. I'd be interested in seeing what they look like. Also, where did you get them from and how much did it cost?

I would imagine that the harness is already there, just not used. However looking at the headlight stalk I would think that needs to be replaced or is there a separate button for the rear fog light? On our Mercedes the rear foglight is part of the headlight switch and it's all as one unit. Pull out twice to get the rear foglight. I would think we would need something on the stalk.. possible even needing coding via techstream.
