I'm going to be adding a backup camera to my 2002 Avalanche tonight. I am going to use a SPDT switch, so it can either come on whenever the truck is in reverse OR whenever I want.

As I understand, for the reverse part - I will tap the light green wire in the MBEC behind the brake pedal - correct?

For the "constant on" - I'd like to find an in cab source that is hot anytime the key is on. Advice on that?

I am using a relay to power the camera/screen - so the power source only needs to be able to supply enough power to switch a relay.
