Installing a Wolfbox Tripro G900 in a US 2025 QM with the dual battery set-up, but having difficulty locating the reverse lighting wire which (when powered) activates the reverse functionality of the rear camera. Anyone know where the location is of this mystery wire? I looks like it may be a pink/purple wire, coming into the rear underseat area, but I’m not 100% sure. I’d rather not disassemble the entire rear section prior to know the general location. For obvious reasons, I’d like to splice it there versus the outside of the vehicle.
