In our experience, the 2015-2017 F150s made in the US and Canada do not need the CANBUS resistors. I would try to install the lights alone, and then get the CANBUS resistors later, if it turns out you need them. According to CrystaLux, you can fit the lights, drivers, and CANBUS resistors can fit inside the low beam housings without modifying the dust covers, though the fit is tight.
