Need to kill ECU for Car Alarm
Hi, I need to know which of the wires going to the ECU I need to immobilise for the new car alarm I've just bought. There seems to be 4 main power wires, Yellow constant, two red power wires and a Red/Green wire which only powers up on ignition. Is this the one I should immoblise to stop the ECU from working?
Also the wire appears to be pretty thick(high current) so will this cause any issues going through the car alarms relays?
