Update to this diagram for anyone else following it.
Pin 13 in the diagram showing video+ should be Pin 12. (so put a switch/relay on pin 12 not 13 as shown)
Pin 14 in the diagram showing video- should be Pin 24. (so join video- to pin 24).

You can also use a DPDT relay, no need for 3PDT relay as shown.

Here is a bad update to the diagram.



Attached is a PDF (extracted from the Toyota manual) with all the pinout information for that connector.
