Wiring Diagram help... am I reading this right?
 L and R park lights GREY/WHITE and GREY... Low Beam=YELLOW... but if it passes through the Combination Relay and Hi Beam is selected then Hi Beam=White is also used. (both is used?) What is N, NS, NSE? And why does NSE end up with 58R? I assume they're for the fogs? Can't make out how it works...

The picture is fuzzy and hard to make out.
The low beams are on when the high beams are on. The "Combination Relay" is actually the high / low beam switch. Power for flashing the high beams with the headlights comes from the top right fuse. NSE is feed from the parking light side of the headlight switch, it just happens to be joined at a fuse terminal. N and NS are the fog light outputs each going to a individual fuse then to the actual fog lights.

Thanks! That's a screen shot... it's supposed to be big, I think it was resized or something.
 sorryHow did you come up with the N NS NSE part? Is there a resource for this? Or was it purely from the diagram? I want to be able to read off diagrams.

Deducing the function of N NS NSE 58R was purely from reading your post, looking at the relative sizes of the blurry wiring picture to find their location then looking at power flow.
Most modern German wiring diagrams have battery + at the top rail and Battery - at the bottom. The diagram you show is a hybrid with + near the top but, it is in the format of a GM diagram. ( General Motors ) To read a wiring diagram, start at battery + then follow it through the circuit until you hit battery - . The stuff in the middle either protects the circuit ( fuse / circuit breaker ) , switches the circuit ( switch / relay contacts ) causes another circuit to operate ( relay coil ) or consumes power to make something happen. ( Light / motor ) A starting point to understanding a wiring diagram is to understand how individual parts operate. After than it is just following the wires on the map. Also, switches are usually shown in their " neutral " state unless otherwise noted. ( off position , no pressure, engine off. ) Last edited by 97 SL320; 10-07-2012 at 09:22 PM.

Oh, something else. If a diagram says NCA, that is No Color Available This is typically used when the part has a short sub harness and really isn't considered part of the main harness. ( Like a glove box light socket that has 3 inches of random colored wire )

The main thing is that the letter designators they give will be printed on the switch or module next to the output pin.
