I have the same connector on mine as well and believe that is power. I just now started getting parts in and will start on this soon. Are you planning to wire yours up as factory?
If so I think we use the Dash Left harness connector. This is what goes back to the BCM at locations C1:1 and C4:13 in order to use the factory headlamp switch.
Has anyone switched out the headlight control for the head/fog light control and had success. It’s a 30.00 part if it’s an easy switch. I have the auxiliary switches, which is the way I’m planning but that could change maybe.
