I've got a 2001 4Runner Limited 4WD and am tinkering with some of the interior lighting. I want to build a new control box that will cause all the interior lights (map, front dome and rear dome) to come on when the factory alarm is disarmed, or any of the doors are open. I also plan to incorporate a delayed off circuit so they will stay on for a time after the last door is closed. In order to do this, I'd like to have a more detailed schematic of the combination meter in order to know exactly what I'm interfacing to. I've downloaded the factory wiring .pdf's, but it only shows the external wiring connections. Does anyone have something with more detail, or maybe someone else has already tinkered with this?
