Would you then consider wiring a momentary double throw switch or a couple of buttons that would let you select the side cameras independent of the turn signals?
You won?t be looking for the a bouncing signal. That happens in the turn signal output The signal being used to activate the turn signal from the lever on steering column will be a solid 12volt signal. In the good old days, this signal fed a special type of relay that utilized a bi-metal switch contact that would open and close with the heat from the current load of the bulbs. That was how you knew when a bulb was out, because your signal would stay on constant (not enough current draw to make the switch heat op and go open circuit momentarily). These days, turn signal modules are all solid state, but they are still triggered by a solid 12v signal from the steering column selector.
