I noticed on a lot of the Gen 2 titans you can activate the Trailer Light Function check on the truck by pressing the lock button once and within 2 seconds hold the lock button down when you press it the second time and the horn will honk. Let go if the button and it tests all of the lights. This fuse box under the hood has the relay for that function but which relay is it? The Blue or Black one? Mine only has the Blue one so I ASSUME it's the Black one that makes it work.

Any input is appreciated
