Hi guys,

I am new to this forum,i run several Bmws 74CSL,84 b9 e28 etc

Wondered please if anyone has knowledge of electronics swap over needed for above project? My 96 525 e34 touring has ews,and having done swap car fires and stalls.

ECU, bonnet loom,instrument cluster all changed with running gear. I read somewhere relay arrangement under back seat , needs to be changed also.

Is anyone aware of whats needed with this set up oF EWS car etc to an older e34 M5 3.6

Thanks guys Hart 420R
