Shortly: I installed broken carvox alarm, it still able to produce lock pulse when I start driving (releasing brake pedal) and unlocks driver door when I switch off engine.
I feel sorry to everyone who cannot enjoy such convenient and simple feature in $30k car.

Connections: you require 5 cables from under the dash. I managed to get it without cutting anything.
Warning: there are no wiring diagram, I recommend disconnect battery to avoid Air Bag deployment. <2007 users should deal with locked radio then.


Set of cables from ignition block.

I trace them to more convenient locations.

1. Black 12V.
2. Blue Ign 12V. Traced to fuse kick panel and intercepted in some green cable after fuse. I think it is fan power or etc.

3. Ground cable: bolt at the kick panel

4. I could not find lock/unlock cable by myself. Some guy in internet sent me help for 5$. Blue cable near fuse box.

5. Finally cable from brake pedal

My car is still under warranty, so I used interceptors so I can remove my patch almost without trace.


Connections to Carvox(former Radiostar) alarm done accordinly to instructions. Blue Locl/Unlock cable connected as negative multiplex, where lock connected using 1K resistor.

I was not able to find out how to unlock all doors, unlock unlocks only driver door.

In progress:
