190e questions, MAS sensor

[css190e]

Hello all, love this place! Have a 1991 190e 2.6, While in the junkyard, found a 1990 190e 2.6 and have the following question: Can I scrounge the
MAS air sensor , ABS control unit,ECM and Ignition control module and use it in my Benz ? I am rather new to the world of benz. The donor car is smashed on the drivers side ,so I assume it was running when it "died"
I know the price of these parts new is pretty high, but it would be nice to have some spare parts such as this for the future. the yard wants 35.00 for each "computer" a good investment or heartache? any info or links would be appreciated thanks to all !
