I have a 1992 300SL 129 model 12valve 103 engine and I am looking for a wiring diagram and pin out info for various units can any body advise where I can get this from. I live in the UK and have drawn a complete blank with the dealers here.

Any help would be greatly appreciated

Thanks

 

I found the ETM (Electrical Troubleshooting Manual) on the internet some time back, try for that - mine is a single 170MB PDF, of some 1325 pages!!

It is just the ticket. Has all connector locations, module locations, covers all models thru to 2000, and is genuine, all the wire colours match. All options like ADS, etc. Test conditions on pins like ohms or volts.

If you dont find it elsewhere I could send you one. (I presume the same information is in the full service manuals that are on some of the sites that offer manuals, others may confirm this or not). Email me if you want.

What component specifically are you intersted in ??

TO GREGE !

If you do come back from time to time to this thread I would dare ask you a copy of your ETM PDF as I have got some electrical problems with my 300 SL 24 from 1991!
First of all the "arceau of security" stands up any time I fold the soft top and the yellow light brights on the instrument panel in the meantime the red diodes lights !
And now I meet a new problem regarding my air conditionning ! I just filled in 413A refrigerant gaz but the compressor does not start !

Thanking you in advance please let me know if you could help me

I got mine from www.alldata.com. I zoomed in on each of the several pages for printing the diagram and printed them. Then took the pages and lined them up and scotched taped them together to get one large diagram of what system I wanted to look at. Easier to follow. get a code reader. Have fun, just keep telling yourself it's a hobby.

 

If you get the Star DVD service disc, it allows access to the online electrical diagrams.

 

There are a few reasons why the AC Compressor might not start after filling. 1. is there a low pressure switch? Is there a high pressure switch. Both are protectors of the compressor.
If you filled the AC system which side did you fill the high pressure side or the low pressure side?
Check Schrader valves for leakage. It might not have centered and left you with a leak.

 

Hi, new here , has anyone have a wireing diagram for the radio circut ? 88' 560SL

 

ME too to be sent the ETM pdf please (thanks in advance).

 

I may be wrong, but wouldn't a 1991 AC system use old R12?
