There is a lot of talk about the cruise control unit under the dash, and how to fix it once it has gone south. There are photos on some of these threads as to what the circuitry looks like.

The fact is that many of the boxes are different. For reference's sake, I added a photo of the one found in our 1989 560 SEL. I have highlighed the capacitors that need replacement, and put their specifications into the photo. In my case they were six. Note that Radio Shack does not have these same ones. You can try ones with the same Farand specification, but higher voltages. Or you can go and get the precisely same rated capacitors at places such as US - Electronic Components Distributor | Newark.com (they are cheap).

Here is the picture (note that the 2 MicroF capacitor may actually be 2.2 MicroF - I am still trying to figure this out):



I will follow up as to effectiveness of the repair once the capacitors I ordered have arrived, have been installed, and all the other solder spots have been refreshed.

UDATE: By Micro I mean "μ", and the 2μ2 is indeed 2.2μ.
