Wiring diagram and pin outs for V6 engine control unit

Hi, I am petty new here and have been looking for any links/info on finding details of the pin outs for the ECU for a 2000 SL320 with a V6 112.943 engine. I have spent he last 3 hours searching on here and google etc. I assume other vehicles with the same motor use the same ECU like the S320 or ML320

Any help would be appreciated.

Thanks

Do you run a business, then you can purchase access to the same info on-line here:
Daimler AG - Service & Parts net

Unfortunately this is not available if one does not have a VAT account.

Would you mind explaining what are you after with the pin diagram, do you have some issues that you want to diagnose?

The car is my own and although I do run my own business it is not VAT registered (and has nothing to do with cars)

I am after the pin outs to sort out a problem caused by a garage. I had the car converted to run on lpg on Monday. They have spliced into the loom at the ECU. My understanding is they will have cut in to each injector signal and an rpm signal and a ignition controlled +ve. The problem is since fitting the engine malfunction indicator lamp no longer illuminates when the ignition is switched on. So I want to be able to check exactly what the wires are for they have spliced into and if there are alternatives to try to sort the lack of MIL.
