On your new truck the access port for the antenna lead is in the dash behind the radio screen. I am unsure if a FAKRA connector will work with this and I have been afraid to pull the dash apart to check.
Have pulled my 2016 GMC radio to install SiriusXm external antenna with FAKRA connector. Found some good youtube videos first showing how to do it and color of Satellite radio wire at back of radio. Quite easy to do actually. Use plastic tool to pry silver plastic surround off. It is held on with clips. Right & left side clips can be stubborn but they do unclip. Use socket to take out 4 bolts holding radio in. Carefully tip radio out from top and find something to rest it on as you cannot take it completely out of hole. Many wires connected to bottom of radio but enough slack to access antenna wire & unplug OEM & reconnect FAKRA.
Hope this helps.
