Turn signal to activate passenger side blind spot camera?

[Neil Sears]

Hi all,

I use my Wolfbox 900 pro as my back up camera which leaves the back up input on my 1.5 DIN CarPlay head unit unused.

I was wondering how I would wire it to activate and switch inputs once I engaged my passenger turn signal so a third camera above my passenger side mirror would feed an image to my CarPlay head unit of my blindspot?

Either find a steady-on power source that is activated by said turn signal - or - use the flashing signal as a source to trigger a re-triggerable one-shot of sufficient duration.

I was thinking a relay with a long turn off, or maybe an RC circuit with RC high enough to hold the relay open until the turn signal cycles back on?

Those are both a form of one-shot and should work fine.

In the 06, the flasher relay is basically on top of the steering column.

Note, my Chevy does this when I have a trailer hooked and it's more annoying than anything.
