Wiring diagram
 

Hi all can anyone help with a wiring diagram for 2009 WRX Impreza Hatchback, having trouble fitting a new alarm and this is needed for the pin set out

Out of curiosity why are you fitting a new alarm when the car comes with an "S" model Sigma alarm?? which is fully integrated into the wiring system, including the keys for keyless entry??.
Unless we are not talking about a UK supplied model??

Its a new Sigma S but the wiring is completely different on the harness plug to the unit and the car. Alarm guy is looking for a diagram, waiting on Scorpion to get a reply from Subaru but they are dragging their feet in supplying.

Should be an S34 model if its remote Keyless entry ??

Sigma S fitted, new Sigma S purchased. Keys, and fob entry, keypad internal Scorpion supplied with photo prior to purchase.

Would have thought swapping "like for like" there wouldn't be a problem and would be unplug old and plug in the new and then setup (pair) the existing keys to the alarm.

So did we but obviously not, hence why the ask for wiring diagram?

So what's different to the two sockets shown above?

Nothing just the cable colours different on the new unit to the old one, so pin numbers don't correspond, also more cables out on the new unit. Scorpion say its a very early conversion and need diagram from Subaru hence why I'm looking. If it was a plug and play i wouldn't be asking would I !

Just trying to get things clear as to your problem.....

Subaru have been fitting these with "from the Factory wiring" to Hatch models since 2007 so wouldn't say a 2009 model was an early conversion ( assuming it is a 2009 model rather than a late registered MY08 WRX).
The wiring colour coding will not necessarily match any loom supplied with the new alarm as it has been "incorporated" into the Subaru looms with its own colour coding scheme. The new "supplied" loom will have more wires as Subaru doesn't use all the available connections.

There does appear to be differences in the wiring setup between MY08 and MY09 Impreza wiring ( which includes the narrow body WRX) however they are incorporated into the existing loom.

Thanks for your explanation but i still need the diagram as im not a tecnical person but the guy fitting is, so my explanation is what i have observed. Just need the diagram if no-one can help thats fine. First Registered: 01/04/2009.

Original unit fitted to car

Strange that it's the full blown S30 CAT1 unit rather than the S34 CAT2> CAT1 addon unit.
Reason for replacing it?

Would need either the 10th character of the VIN or 4th character of the Applied model code to confirm Model Year.
VIN plate should be at base of B pillar on passenger side - open both doors to get a clear view. There may also be a white sticker near it giving alarm details.

If you can confirm Model Year using above criterior will send you correct year Alarm system diagrams from relevant Subaru Workshop manual by email.
