Hello! Just purchased a new to me 2014 Sierra WT RCSB. I want to add a dashcam but would prefer to not have to run all kinds of new cables through the truck. I believe I can tap pin 7 in the overhead console connector which is labeled as "Inadvertent Power Control" but was hoping someone could say for sure what that pin actually does. As it is a WT there are not many pins populated on the console side of the connector. If I can add a pin to the connector for a switched power line that would be great as well, I just need to know what pins I need to purchase from Digikey or whoever might have them. I know it is a Delphi harness, I am just not sure if there are different pins for it like some of the other connectors in these trucks. Thanks for any help.
