I would not swap the entire harness, just the parts you need like the GP circuit, etc.

I am not real familiar with MB wiring, but I am familiar with GM wiring. The same model car, but with different options would use the same harness, but leave out the connections for the different options. That is how I added "factory" cruise control to an old Pontiac I had. I found the LJ model and took all the parts off, and took the wiring harness just in case.

If you have wiring schematics for both cars, you should be able to get every thing hooked up with a little modifying.
