dont think you will find one as evan the new haynes books dont have wiring diagrams only block diagrams as with the wiring diagram you can bypass the factory immobiliser.which means less work for the dealer when the immobiliser cuts in for what ever reason

If you don't have a multi tester an easy way to find a constant power source is to take a 12v bulb and wrap the bared end of a piece of any kind of cable around the silver portion of the bulb. Tape it with duct tape or similar to prevent a short circuit. Attach the other end to a bit of unpainted bodywork or bracket. Remove the keys from the car. Now all you have to do is touch the centre lead terminal on the base of the the bulb with any of the wires you want to use the one that lights up the bulb is your No. 1 choice. Remember that the constant supply lead will need its own in line fuse.
