Question 1

I want to inputs to for turn single and backup camera as i turn/backup. What do i need to make this happen? small digital timer - parts/list/help plz!

Accepted Answer

ok, so there is a review on here that lays out adapters and what not for the typical setup.  (male to male, etc)    I don't think you will need a timer per say, but when I wired up my front and rear cam (front on toggle switch, rear off backup lights) I had to use diodes (also found on here) to splice the power into the radio signal input.    the diodes allow basically one way power, so you do not feed back to the other source, or over load your input on the radio.   the rest is simply finding power sources for the cameras,  and wiring them in.   I ignored the 'automatic' input, because I wanted mine to show backup whenever in reverse, even if my front camera was engaged.  you might want to do the same, but testing before tucking your wires away is a great idea to make sure its all setup.

Question 2

Can i use this switch to go between 2 reverse cameras? I have one on my bumper and am adding a wecond camera to my headache rack to help when backing

Accepted Answer

Yes.   A diode may assist with the radio trigger wire

Question 3

Is there a single trigger output that will cause the reciever to turn on the Video input?   Otherwise, what tells the receiver to show the video?

Accepted Answer

In an existing setup, there is already a trigger to the receiver.  Inserting this device does not change that.  It adds the ability, once triggered, to switch the input to one or two other sources.  In my case,. I took the existing trigger (reverse) and wired a 3 way on-off-on switch to enable camera view 2, 1, or 3, depending on whether I wanted front, back, or bed view.  I then took a second, and wired 12v and reverse to the head unit reverse wire so I can turn on the camera, turn off the camera, or have it on when in reverse...

Question 4

What is the response time -- the time between applying 12v to the purple wire (for example) and when the picture shows up on the monitor?

Accepted Answer

It is pretty quick.   Mine runs a few cameras. Pop into reverse and its on the display.
