i finally got the chance to get the computer out of the car but the only problem isthere are two computers and i dont know wich one to get the first one is bigger and has the numbers(bosch#0265101018)(mercedes#0055452132)


then there is the smaller one wich has numbers(bosch#0280800216)(mercedes#0055457232)



the smaller of the two smells kinda like an old tv or old computer not really burnt but you can tell its been used
the bigger one smells like just dust
the mechanic looked it up in alldata and it didnt say wich one was wich.
any help is greatly appreciated btw he said he tested the wires so if anyone knows wich one of these computers has to do with the spark please enlighten me
