In addition to reverse i want to make turn signals trigger camera inputs
As xenarcs will automatically switch to the composite when a signal is detected i was thinking of making a hardware only black box to accomplish this. only thing is im not sure if it would work ive got most of it planned out only thing i cant figure out is how to make all 3 leads selectable so that the video signal doesnt bottle neck
heres a diagram of what im trying to do ...
eg a dumbed down version of this
