    I installed LED running board lights on my 2005 4Runner by tapping in to the front door courtesy light. The drivers side went well. I did the same thing on the passenger side and somehow lost ground to the courtesy light. I can ground it but the light stays on even with the door closed. I checked the (yellow) ground wire from the light to the connection inside the vehicle and it is not broken. Anyone?

    Did you sketch out a schematic prior to wiring? I usually do this so I can keep up with what I have done wiring wise. I would be guessing it would have something to do with the door switch or door switch wiring.

    as far as I know all those lights are ground switched, meaning hot is there all the time and the door switch makes the ground connection for lights to work. so its not supposed to have ground until the door switch does that for you, maybe your door switch is shorted and grounding all the time or you the lights ground out through the mounting body, if that is the case you need to get a different light or find a way to sever to ground circuit so its only done through wires

    My next option is to swap the switch with another door and see what happens.

    Well it's not the switch. I disconnected everything I did and it is now hooked up like factory. Yellow to yellow wire on the light and red to red. Light will not come on unless it is grounded to the yellow wire. By the way, I'm tired of this light.

    Solved. Somehow I lost ground between the jamb switch and the light.
