Do ya mean the immobilisation points?
One can be the wire for the starter solenoid on the starter motor. Normally a purple wire. And being EFI u can also use the power wire for the fuel pump, or even the power source for the tachometric relay could be used.
The ignition might be able to be used, I'm not sure how much power goes through the wires, but I guess ya could use it if ya hook up a relay. The input and output signal just use the ignition wire, earth it out, and the power wire goes to ur immobiliser, then the paired wire goes to a power source, so when the immobiliser is switched off it gives power to the relay for ur ignition to work.
Altho straight outta the igition, there's 2 wires which power the coil, one for when ur ignition is in the start position, and the other for when ya ignition is in the on position, they eventually go into one wire and off to the dizzy.
