After installing the Tekonsha T-One wiring harness with the 4-pole flat connector (part number 118778), my backup camera on the truck does not work. I don't understand your reset instructions above. I have driven the truck several times, but have not connected a trailer to the harness yet. Can you give me a little bit more detailed instructions? Surely this cannot be just coincidental?

@Jim If you're wanting to ensure that the system is fully restarting then I recommend just removing the key from the ignition and disconnecting the battery cables and waiting about an hour for the electricity still in the wiring to dissipate. You can then reconnect the battery cables and the system should fully reset since it lost power. I would not say it's coincidental that your camera isn't working properly but I do think a reset will help the ECU recognize the new trailer wiring and properly function going forward.

I did disconnect the battery, but only for about 30 seconds. I will try the longer time.
