Hi All,

Does anyone know where I can get a wiring diagram for 2010 Impreza. I need it to work out best circuit locations to install kill switches.
Tried a few sites that say they have all the manuals and wiring diagrams available for download but they all want you to install browser extensions and do surveys etc. etc.
I'm guessing the circuitry might be the same as that for the 2009 but not sure. Can anyone point me in the right direction?

What kill switches are you trying to install and why?

Have you considered a decent alarm system - much easier than multiple kill switches.

If you do go down the switch path - you'll want to cut ignition and fuel.

Igniton can be found under the steering column - you'll see a connector with usually 4 heavy gauge wires coming from the Igniton barrel. Unsure on the GR's but the GD's are either solid white or white with black trace for ignition cut. I'd recommend using a relay to break that one unless you have a switch with 20A+ rated contacts.

Fuel for the GD's there is the relay located behind the passenger kick trim. You can cut into that circuit like the alarm systems do - or try locate it around the fuse box area.

In all honestly for the headache I'd just get an Autowatch fitted. Cute fuel and Igniton really easy and without the messing about.

The entire reason to have kill switchs is incase someone steals your keys. An alarm system (typically) is simply disarmed with a remote key fob, which is clipped onto the key ring. So offers practically zero protection against this.

(Yes the some systems such as the one you mentioned can be setup with anti hijack or anti key theft switchs. But more often than not, these features, even if supported by the alarm, arent setup/engaged.)

A simply hidden switch can be a good way to protect against key theft. The cars themselves are basically impossible to 'hotwire'. And an alarm with addition kill circuits, but disarmed by a remote key fob on the key ring offers zero extra theft protection other than a siren to warn and deter. And a flashing light on the dash to hopefully deter break ins.

Autowatch 956 I should have added - keypad alarm will probably suit the application. Use that along with an extra ignition or fuel kill switch.
