Has anyone wired the backup camera to a switch so you can active when you want and not just in reverse? I have the factory radio. Is there a power wire going to reverse to activate the camera?
Which wire provides the image/actual video. I struggling over here. SorrySounds pretty simple.
You can use a 30-Amp SPDT Relay.
How to wire the switch and relay:
One side of the switch goes to ground.
The other side connects to pin 85 on the relay.
Pin 86-87 connects to +12v constant. Which is the White Wite on the 3-pin radio harness behind the radio location.
Connect pin 30 to the Reverse Wire on the back of the aftermarket head unit. You can use both, the reverse wire and switch wire at the same time.
So, whe you shift into reverse you can see the camera image. Or if you flip the switch while you are driving, you can see the camera image.
Please DM me if you have any questions or if you need help with wiring.
I am not sure what the pin out is on the main harness to the factory black box for the media system. I will have to do some thinking and see what I can come up with.One more quick question (maybe), in your original post you said the reverse wire on the aftermarket head unit. I have a SL so I will be using the OE unit. What is the color of the wire on the three wire connector that supply's the image from the camera that I will need to tap into. Assuming that that is the wire I will need to use. Just read that, I hope it makes sense
