side view cameras

Can't help with the wiring, but on my in dash display unit it has a delay that keeps the cameras on while the blinkers are flashing.
Maybe yours does too.
do you have a manual on the display unit?

there are 2 wires coming out of the column. left and right. the flasher is wired on the power wire going into the column, and works with both/either.

I'm not real sure how the side camera inputs work tho. perhaps they have a delay?

Thanks for the input. That confirms one assumption. I do realize that hooking up past the thermal flasher will cause the screen to turn on and off in sync with the flasher; what I don't understand is, when the signal arm is pushed up or down (rt or lt) how does the circuit know which side to activate, if, as you say, there is only one wire coming from the column?
My next assumption is that there are two wires coming from the turn signal arm at the steering column to the thermal flasher. I just cant figure which two...

oops.. try another idea

the wire there is only (1) flasher for the turn signals, and one Hot wire inside the collum
the wires coming out and going to each side (right-left) blink/power on off from the flasher

do you want your camera signal/picture going blinking on off

you will need manual switch form a separate hot source
or get fancy using a separate hot source and 'latching relays' that come on when the turn signal for that side is activated, then time out after your turn
