i have a Toyota corolla xli 2012 and I want to install a security system/tracker in my car. I understand how it works and have the wiring diagram. However I need to find appropriate wires under the dash or steering to install it.
- i need to locate constant 12v supply which is always 12v regardless of the ignition switch position.
- need to locate ignition 12v which is only 12v when ignition key position is on and 0v when key position is not on.
- the last wire I need to know is the door trigger wire, which gives toggles voltage when door is opened or closed.
- Also how to remove the panel below the steering to expose cables .
Any guidance on this would be appreciated.
