Own the 14 Silverado since Jan 02 2015, and never use the Pandora radio Therefore, call GM and OnStar for instructions, the said never heard about it and never heard about BYOM. I ask the OnStar guy for a software update, the turn out told me THE 4G LTE UPGRADE HARDWARE IS FREE!!! IT ALSO COME WITH 3 month 3G data and 5 year base plan. SO, guys don't let gm take advantage frim you. Holp this share helps Sent from my SGH-I337M using Tapatalk

Love to trade, but I live in vancouver

just put the led strip with factory bed light wire Sorry about the bad pictures

In fact, the plug under the bed has a 3rd brake light connection as well, but little hard to add to the harness

yes it does

Then you just need any universal led (27 from Walmart. ca) and run the wire yourself. Different story if you have the bed light already
