Yes, the circuits you found for installing the P3 part # 90195 that you referenced in your 2016 Chevy Express Van are correct. The CHMSL circuit stands for center high mount signal lamp and is a dedicated brake light circuit and runs to the red wire and then the blue wire of the controller goes to trailer auxiliary circuit.
