Does anyone have electric brakes on their trailer working with their XC90 Recharge? No one at my dealership is able to guide me. I have the factory installed trailer hitch kit with 7-pin connector installed. I need to get 12v power to Pin #4 (the 1 o'clock position) and this pin is currently not getting power when tested. I also see that Pin #2 is designated as a spare and electric trailer brakes are noted for this pin in their web instruction below. Yet no one at dealership is able to guide me on how I can get electric brakes working with my vehicle. Hoping someone out there can help me.
