I'm an emergency vehicle upfit technician and am looking for an overall wiring guide for the 2021 F150s. I've found that some of the wires are the same as the 2015-2020 trucks, but some stuff is completely different. I am having trouble finding the Park signal in particular. Also, is there and ignition signal or start signal at the BCM? The Ignition switch is a PITA to get to in these trucks.
