Update: Want to let you know that the RSG harness has the exact same connection as the Toyota camera, and the other end is probably the same (they state that they are Toyora connectors), however the different colored wires are not connected to the correct terminals on the furnished connectors, so you will need to make sure the correct vehicle side wires go to the correct terminals on the relocated camera Also on a GX 460, the second harness connector will not be used, as there is no place to plug it in, at least inside the GX rear door.
Also: I received the harness at a reduced cost in exchange for writing up a procedure for the GX 460.
