Is there a way to turn off the light in the trunk when the trunk is open?
I didn’t realize it was for a new Giulia because I’m an idiot lol. M Smith is right, on a modern CAN bus vehicle there isn’t much you can do that’s worth the effort unless there’s a settling in the main console.I would not count on that. I've not looked but that trunk light will be connected to the cars lighting "computer", even the 164 had that feature. These circuits are also wired through the proximity switches on the doors and, in the case of the trunk light, to a timer function that turns off all interior lighting after a set time in order to protect the battery if a door or the trunk lid is left unlatched.
If you cannot locate a switch in the trunk (older cars had such a switch somewhere fairly handy but separate from the switch actuated by the lid opening) is it possible there is an option in the various computer settings accessible from the dashboard screen?
I did this and after 5 minutes the light was still on in the trunk.I believe the Giulia has a timer which turns the light off automatically; easy enough to check; leave the trunk open and wait till light goes off. Probably same amount of time for interior lights to turn off.
