Hi, I'm installing two side view cameras on my 2017 3500 duramax. I require a trigger from my left and right indicator circuits and was wondering where to tap in to the existing circuitry. The BCM (body control module) has two inputs (pin 12 X3, pin 24 X3) that appear to be relevant. Can I simply tap into each of these or is there a better place? Am I correct in understanding that the turn signals from the S78 switch pull the BCM inputs low (e.g., they apply ground to the BCM) in which case the trigger will be low as opposed to high? Is it 12v when the turn signal is not active? Thanks in advance.
