Thanks for the reply.
Was toying around with the idea of activating a device like an external lamp or speaker system to the startup sequence when I unlock the car.
How would I be able to watch for this information? what are the tools/equipment that I would need? Some direction would be helpful.
You can probably do this btw (the external lamp anyway) by piping directly into the same circuit that the dome lights or factory illuminated rockers were wired for that.
Why would you want speakers enabled when car is unlocked?
