I just bought a 2014 Silverado 4X4 LT with no options but does have I04 and I want to change to I06. Other options that I am adding is PW and PW but the dealer is giving me so much pushback. I bought the necessary GM parts including door panels and switches. I don't care if the options are programmed into the BCM and prefer them to stand alone like older vehicles. I also bought the door harnesses to the "A" pillar but need the electrical connectors to extend the wiring from side to side. I bought pieces of "A" pillar body harnesses but can't get the pins removed after moving the retainer to one side. Is a double pick needed? Thx, Obi One
