Have you hooked up a diagnostic tool to monitor the operation of all these components that have been replaced? How did you come to the conclusion that you need to find a ground wire to the processor? Side note: how much money did you pay for all those parts? If you had the vehicle evaluated by a qualified technician, my guess is that it would have cost far less to find out definitively what is wrong -- with far less replaced parts.
