There ae two security sytems. the Passive Anti Theft system and the Active Anti Theft system.

The PAT's is built into the ecu and is an immobilizer the AAT's is a seperate alarm unit. But the AAT's does take a signal from the PAT's.

The immobilizer will run independant of the alarm.

So yes its a case of seperating the engine loom from the car. With more advanced comunication between all the cars systems its case of seing if I can keep the ecu happy to run full power.

The Pats is really no big deal to use, its just four wires and an antenna around the ignition barrel. You dont have to do anything with it, it is completly Passive.
