Default Were does the original alarm/imo split startermotor cable

I have had a long time problem that startermotor
don’t pull all times.
I have previously changed ignition switch and startermotor.

on a 964 turbo the cable goes straight no relay according to wire diagram.

anyone know it’s way and we’re the split could be?

- there is no “split”, the starter has a direct cable connection to the positive terminal of the battery

- alarm/imo has no influence on the starter, in case of activation only the ignition and fuel pumps are not supplied with current.

Most likely causes of the problem:
- cheap replacement starter (guess how i know)
- body/gearbox ground strap
- battery/body ground strap
- Terminal 50 of the ignition remains off

but when i not have deactivate the alarm so the small light is constant the starter never turns so it has to be "split"

i have same remote on Ferrari 355 but there the starter turns but no start before deactivate alarm

I found the ECU under passenger seat inside closed metal box 993 618 959 00 Steuergerät Wegfahrsperre
so no i will try following all cables an see what i found.

Yes, start searching immediately. Only then read again and understand what I have written.

And if you had written from the beginning that a 993 immobilizer control unit was installed in the 964 turbo, I would have put you straight on the right path. Your welcome.
