Control unit – replacement 850 T5 ́97

Huhu My dad asks me to ask the knowledgeable ones here among you what it looks like to replace the control unit, because for some time now some lights have been burning for a long time despite all repairs.. This is (believe) ABS, Antishlupf? and Motorelektronik lamp. I have read a lot about soldering here?! Can someone tell me something closer? Because I think the replacement control unit what he bought can not be used???? I hang a picture of the original built-up (bosch) and the spare part on. Thank you very much.
