peugeot 207, alarm wiring?

This is going to wiz you off but Peugeots are nightmares and don't use regular colours.  You have to test everything, also they use their own version of CAN called VAN, also I believed that they are not normally sold in North America so Fortin etc won't have any parts. You need to test EVERYTHING before installing because they change their wiring colours every three months or so.

The good news is is that most things are accessible through the BSI fusebox. Lock motor wires, indicators(hazards), door contacts (diode block and diode join) Drop the steering column cowling to get at power supplies ign (x 2) and starter. Contact me if you are including R/S because I have type specific advice on this. My experience is on the 206 but the last year of the 206 used the 207 wiring.

You really don't want to know this but on late 206/7s there are two ign leads BOTH of  which stay live under cranking and BOTH supply the ign. If you cut  EITHER it will immobilise the car. When we do a Cat 1 alarm*  it obviously doesn't matter,  you  cut one of them and the starter. Unfortunately when you add an R/S you have to power up both as the primary ign. The one you cut has to be the one controlling the brake  lights, if not when you get back into the car with the engine running , turn the key and push on brake pedal nothing happens!  Also forget tach from an injector port, they are sealed in epoxy!!  You have to get tach from the controller  which is in front of the right hand wheel arch, don't ask me what colour because every time I do one it's a different colour, even the factory hood switch (if fitted) changes colour from the switch to inside the car.
