just because i don't like threads that don't end
i just got today the parts i order from fleebay (under a month from china is not bad).
the big board is the timer, that has a NO/NC 30Amp relay.
so i can connect it directly to the fog light wires.
the small board is the photoelectric sensor that will control the timer.
so basically it is going to be connected to the interior lights, and will trigger the timer only when it's dark. the lights will stay on (after i lock the car) for 10 seconds or any other settings i will put in the timer.
so before i start i want to modify the components, and check the power consumption.
if it will be within reasonable values, i will install it.
will keep you posted when i make any progress.
