2018 F-150 STD KEY W/Keyless
I've figured out most of the wiring diagram. The one part puzzling me is the optional "Parking light relay." I understand that I splice one parking light wire, and connect it to two of the relay terminals. Then the other parking light wire looks like I do an inline splice, and take it to another pin on the relay. Finally I need to pull a wire from the 20 pin connecter, to the relay. Finally it shows the +12V 4-pin, do I need to pull a 12v power source to this relay? is that what the diagram is asking?
