Open the full vehicle complaint log (all categories)Missing the wire connector for the puddle lamp installation? although not a safety issue, would like to bring this to attention; wire connectors (and wires) missing on both driver and passenger doors? Not sure if this was a factory oversight, or an error in original wiring diagram of Toyota? If so, there could be other wires missing in the vehicle as well. Hopefully Toyota will look into this and propose a fix for their customers. Thank you
