Help required to find a wiring diagram

[NBurns]

People (I am always tempted to write '"Friends, Romans, countrymen, lend me your ears" to start my posts ),

Okay. The rear licence plate left bulb still seems to be causing an error on the diagnostics even though I have fitted a new bulb. Unless that new bulb is also defective (will test tomorrow now with meter).
Therefore where is one likely to find the wiring diagram online and perhaps downloadable for the wiring between the bulbs and the rear SAM? I have already looked through the mbepc catalogue and the BBBInd.com website and could not find what I am looking for even though I have noted the wire colours for both licence plate bulbs. Any ideas?

Doesn't Haynes have some diagrams in the back ? I'm not at home to check !

Here you go.

... and pop off the drivers side end of the dashboard. There should be a complete fuse diagram tucked in there, along with a fuse board and spare fuses.

Yes. Already have that but it doesn't show what i need. I need the diagram that shows where the wiring goes from the bulb holder to the Sam unit so that I can test that wiring. Because I currently have two unknowns and I would like to eliminate one of them.

Many many thanks for this. I should now be able to trace those wires back to the Sam unit.
Out of interest, where did you get this information from? Was it from your own STAR system or from the internet?

Also interestingly it does not show which relays are which and what they control. Yesterday I wanted to find out what relay position D was controlling. Even though the circuit is simply a bridge wire and not a relay.

And I'm sorry however as a medically discharged veteran of the Royal Navy Submarine a Service and a very small pension of just over £300 a month, in debt by about £12k currently and being snubbed by the DWP, I cannot afford to go to either a Mercedes Benz dealership OR an independent specialist because I would not now be able to afford either of their labour costs. Therefore because I have a background in communications engineering from the university of Portsmouth, I have done all the work needed on my car since it broke down big style last November with a turbocharger failure and an injector seal failure, myself!! Five years ago, when I first bought my Mercedes-Benz, I had the money to buy her and fix her. Now, after major health issues including high blood pressure, high cholesterol, pre-diabetes, severe depression resulting in me attempting to commit suicide Twice because the 'system ' has screwed me and really does not care about veterans, I decided to attempt to fix my car myself. Simply due to the fact that I knew the labour charges were going to be too high. The result of that has put me in even more debt now which I now need to recoup asap. However she now does run and does move. So perhaps you could provide an alternative way for me to find what I am looking for which is not copyright material?!!

Okay. I know where 'my' local library is in Gosport. I will have to enquire where the Hedge End one is.

Okay. Got the meter out and did some checks. Touch wood, I believe the problem is actually a broken part within the bulb holder. Luckily I have ordered a set of LED bulbs complete with holder. So will swap them out on Monday now.
