2018 SCREW - just installed the kit... used JS7Z-19A361-A w/ LED
I used the bracket the brake controller module was attached to... the plastic case was mostly hollow so I used two small screws around the factory "baja mod" like bracket into said module. Very secure and there's access to sensitivity dial. Plenty of room to tuck excess wires up towards the steering wheel and secured with zip ties.
I was able to mount the LED in the OH **** handle (instructions warn against installing where airbags deploy... I like to live dangerously)
The OE instructions which I have access to being a Ford employee
state once security module is installed, only a key ON, OFF, ON is needed for the truck to recognize the new module - remote start, interior motion sensors, all original functionality was retained.
