How to wire a manual switch for backup camera
I would like to add a manual activation switch for the backup camera already connected to an Xovision XOD1760BT in-dash monitor. A couple of years ago I upgraded my motorhome with an Xovision XOD17...

My RV is a 2004 Trail Lite B+ 235s and I think the original Voyager B/W backup camera was added by one of the previous owners. I got tired of hitting my head on the overhead monitor and when I upgraded the in-dash stereo I removed the monitor and fed the backup camera's video feed into the Xovision XOD1760BT standard camera input.
Although I cut the short section of exposed cable at the camera end to put in a weatherproof plug, I'm not sure how/where the camera is getting its +12v power. It might very well be from the backup light circuit, but this section of the camera cable is not exposed.
Unfortunately, the Xovision XOD1760BT does not have a menu option to display the camera feed, only the AUX video feed, and running the camera video into the AUX video input will bypass the reverse-signal backup logic which currently works.
Thanks for the heads-up on possible transmission/computer complications of backfeeding the reverse_signal line. I had not considered that.
Also thanks for the SPDT suggestion. For my situation I guess the wiring would be:
COMMON-Head Unit
UP (Auto): Reverse_Signal
DOWN (Manual): +12v
I may also look for an illuminated switch as a reminder that the camera is in manual mode.
