Security is often provided by "something you have" like a key, "something you know" like a password or "something you have and something you know" like a ATM card + PIN code. For a long time the security for a car has been a key and modern cars have inceased the security by adding a small transponder (RFID) inside the key, i.e. they added a second "something you have". It doesn't matter how many wires you attempt to connect, the ECU will simply refuse to run the engine until it has established a conenction with the key transponder. To add a remote start you have to leave this transponder inside the car, e.g. it is no longer "something you have". There is no way around this reduced security unless the remote start logic is integrated inside the ECU and the extra "something you have" is sent from the remote control as some form of a token over a suitable encrypted radio transmission. A petrol driven engine/cabin heater is a tried technology that will warm up the car without the security and environment problems that a remote starter has. -- G–ran Larsson http://www.nospam.com/saab/
