Ecu and alarm on 964

[Tezme]

Hi Guys

Does anyone have a wiring diagram for the factory alarm system on a 93 Carrera 2 964 Cabriolet. And also for the same car a wiring diagram for engine ecu aswell. I am fitting an aftermarket car alarm and need wiring diagrams urgently to be able to immobilise ecu and disconnect oem alarm system. What part of electrical system of the car does the oem alarm actually immobilise? e.g ecu, starter, fuel pump etc etc. Any help with any of this stuff would be greatful. Cheers all.
