You can find the wiring diagram here http://www.autolib.diakom.ru/CAR/Mercedes-Benz/1995/C220/SYSTEM%20WIRING%20DIAGRAMS/5301.pdf

P.S: C220 uses same engine as E220.

If you are comfortable with rigging your own interface try,

You can monitor all parameters that DAS can.
Will re-check the wiring between the two plugs tomorrow! Also, brought the vaccum pump from the workshop so tomorrow will be test-day!

I am considering buying the Carsoft cable kit to use with that software...

I dont wanna give up on my 220E!
