Floor light question

[jhubbz]

There are three wires running from the dome light. Orange, White and Black. Orange and white are the ones you need to splice into. Orange is positive and white is negative. Normally you would ground to black, but in this case the white runs to the dimmer switch, which controls the interior lighting. I have mine ran this way so the floor lights only turn on when the dome light either turns on automatically because the door is open, or bc I switched the dome light on. I also have LED strips under my door spliced into this wiring to light the ground when my doors are open.
