I want Trunk Lights to turn on using the ambient light button on the touch screen. I don't think making the existing lights work with the button would be simple so it makes sense to run wires from the rear passenger doors light to the trunk and install new led lights. I am just wondering if it is as simple as doing that? I will still have to figure out how and where to run the wires from so everything is hidden. Reason to do it: I've got child seat in the back and tinted windows it gets really dark. I searched the forum and found people changing the lights or attaching a second light by running wires from the the existing trunk lights. Currently we have a portable led torch light in the back which I turn on. the kids play with it and then fight with each other. If i forget the light in the back or forget to replace the battery then I sometimes just turn on one of the passenger Dome lights. Any help or any threads i should look at that would help me do this?
