If someone could point me in the right direction it would be very much appreciated:
1. Where can I purchase the wiring loom from (preferably in UK, but no harm in shipping from Phil if he carry's stock)
2. I see there are upper and lower parts - rough cost for individual and both?
3. I guess I should do both?
4. Does the ETC unit connect to the new harness? If so, I seem recall from memory I need to strip the ETC out also and rewire this manually. Does anyone specialise in this repair - I seem to recall a few US places but anyone know of any UK based?
Many thanks

I'm speaking from 1996 SL600 experience, so there may be differences.
You should be able to purchase at any MB dealer. No one will have this in stock.
As far as I know the only lower parts are the oil pressure and level and alternator, starter harness. I wouldent see a need for both except the lower one is probably under $200 US the upper is probably over $2000 US.
I don't have ASR, I have ESP which has its own separate harness.
I'm not sure what you mean by ETC (Electronic Transmission Controller?) The wire harness connects directly to the ECU (Engine Control Units) Thats the LH units for pre96 and the ME units for 96 up. I was unaware that your car, pre 96 SL 500 had an electronic shift transmission. If it does it is not connected to the engine harness.
In my case the connectors for the ECUs just unplug from the top of the two ME units and are easy to remove. I think your connectors are on the bottom of the box, but my guess is they come out as a separate connector.
For the 1996 SL600 this appears to be a very simple job. Remove 3 connectors from the computer box and disconnect everything from the engine. which all seems to be very exposed, accept I cant say the knock sensors are easy to get at. They might require removal of the intake manifold.
