Wild guess =>

The other chassis wiring is probably pretty close if not the same.

If not (#1) =>

Find the diagrams on startekinfo for the W123 with the M110 engine - that will probably get you quite close to what you have.

If not (#2) =>

If you get really stuck then you could pay for very short term internet access to WIS (available via the startekinfo site) - this is pretty costly but might help soothe the pain...

If not (#3) =>

Ask a R107 owners club for help - joining an accredited Mercedes owners club often gives you access to EPC and WIS which can be well worth the money
