Incidently, the fog/driving lights on the C36 were either fog lights or driving lights never both, I believe the EPC lists two different light fittings for this bumper, "I believe" early vehicles (pre-pre facelifts) were equipped with driving lights, the pre facelift vehicles equipped with fog lights, This I think represents break point in whether relays were fitted.
A quick read of the EPC reveals this to be true
I think the problem with the C36 is that it was only produced for about a year then the 202 facelift happened and some C36s were built as a cross-over. I remember Alps going into some of the oddities of the later-model C36.
"806" 1996 models seem to have driving lamps
"807" 1997 models have fogs
although the lamps themselves are different part numbers, as are the looms I suspect the looms would fit either so you'd need to find out which of the lamp types is fitted to the bumper.
This could be established by providing the VIN of the donor car or reading the part number off the back of the lamps. If you are creative you could try sending 12v into the lamp connector to see which type of lamp it is.

HWA2028200656 - right AMG beam
HWA2028200156 - left AMG fog
HWA2028200256 - right AMG fog
Interestingly the driving lamp loom has a 140 part number but the fog lamp loom is 202. Driving lamp loom is £22, fog lamp loom is unavailable according to the inchcape site but this isn't gospel.
If it came down to it you could make up your own based on whatever you have available - the pins inside the connector can be moved to different positions.
