116.120 vacumn diagram
 

Morning to all.
I am beginning the install process of my Unwired AC servo upgrade. The unwired website shows vacumn diagrams for 107 and 123 series. Can someone tell me if one of those is the same as 116.120? Does anyone have a source for the 116.120 vacumn diagram? My car is a 1979 MB300SD.

thanks in advance.

Have you tried calling their tech line? Last summer I called just to ask some questions and found them to be a very friendly and willing to support their product. Or if a search of this site does not turn up anything try www.w116.org.
Some people have had good luck with the factory manuals on CD, tho I prefer to take a manual to the car.
Please keep us posted as there are quite a few of us W116SD owners out here that would love to upgrade to the Unwired system.
Good luck and look forward to hearing of your progress

All the vacuum diagrams (+ the entire service manuals) you need are in W116.org, in the Library Section, and click on the text Field Service Manual.

Please post updates of your project, with pics if possible. I'm thinking of making this upgrade as well.

Thanks,
