I got your PM as well. I'll reply here so others can see as well.

The 005 545 12 32 is a 10-pin vacuum cruise control unit. So you'll have to have a vacuum cruise unit in the engine bay.

If you've got the later servo/actuator..it'll look like my 300SD:

The 002 545 91 32 and 003 545 86 32 units are 14-pin units.

I suspect Mercedes might have retained the speed signal circuitry from the earlier vacuum units in your MY81 and used an amplifier that was compatible with such sensors e.g the 003 545 86 32.

So my recommendation would be to go with the 003 545 86 32 as per the MB EPC so long as you have the servo in the engine bay.

If you don't have the servo and have vacuum, I do have 005 545 12 32's (I believe..I'll have to double check) and I'm 4/4 on vacuum repairs so far!
