I had tow mirrors installed on my 2014 1500 Silverado and when i put the truck in reverse I can’t turn on the reverse lights on the tow mirrors with the cargo lamp switch, when I push the switch nothing happens until I put the truck in park then they come on with the cargo lamp switch. My dad had tow mirrors put on his 2015 1500 Silverado and when you put his truck in reverse his cargo light switch will let you turn on the cargo lights and reverse lights on the tow mirrors. Is that how the 14’s are compared to the 15’s?
