Second Camera using RCA Switcher

[matthewkristof]

I installed the Sony XAV-AX6000 last year to replace my aging stock radio. It has been excellent but unfortunately, only has one camera input. I've been using the backup camera but recently wired up a forward camera and purchased an inexpensive RCA switcher. It uses a slide switch to toggle between input 1 and 2.

I've gotten it working but want to wire it up to a toggle switch so I can hide this unit in the dash. I cannot figure out how to do this. I looked up some wiring diagrams online for slide switches but most are for 3 or 6 pins, while I have 12 pins. I know there's pins there for the audio connections but I'm just interested in the video ones. The dots in the diagram are the video lines traced to the slide switch. I've tried tracking the connections to the soldering on the circuit board but haven't been able to get it to work.

Hoping someone smarter than me can help me out. Appreciate any help!

How's it going?
Your switcher is definitely not a great choice for the car. Your cameras don't have audio, so you will only be using the yellow RCAs.
A simple dual Bosch style relay setup will take care of your switching.

I added a picture & hope it helps. The 12v in can be controlled by pretty much anything.

Yea, it's not the best option for sure. The headhunt itself doesn't have the option for a second camera or video input, so I was trying to create my own. I managed to add the anytime backup camera employing a simple rocker switch which I use surprisingly much.

Thank you for your diagram. I got the main gist of it. I'm guessing the two lines coming out of the nav radio and two cameras are positive and negative leads, right? Also, do I control the front/reverse camera through the 12V input?
