OK, you folks helped me out with this a couple years ago on a different GM. Here's my deal. I drive a lot at night, and I seriously prefer an old school foot headlight dimmer switch. On my 2004, it was easy to set up with your help. Placing the stalk multifunc switch in high beam mode, and then hooking up the foot switch in series with the wire from the mf switch to the BCM, with one lead of the foot switch grounded, and one not, the foot switch then switches the high beam on and off. I want to do this again on my 2015 Sierrs. I have two questions: 1) is this the same basic wiring setup as the 2004, or is there a different situation on the 2015, and 2) if doable, what is the BCM connector, the connector position, and the wore color for that ground signal from the mf switch I need to tap?
