2022.5 Cargo bed lights secondary switch

[Fla Eagle]

I never really thought about before until a guy I work with got a new f150 and ordered the Ford oem bed cargo light kit and I really liked the secondary switch. I researched this a bit and there were a few aftermarket solutions and no real info on a 2022.5 as the electrical is different. He received 2 of the switches and gave one to me. I ordered the Ford wiring harness and t-tapped them in. It's weird having Ford parts, but I like that it looks factory. I wish it came that way from the factory.

The switch now acts the same as the interior switch and turns the cargo lights on through the bcm. It will time out and turn off if you forget. Some aftermarket options won't

How big of hole did you have to cut and what did you T tap into on the truck side?

I tapped the grey wire coming from the back of the truck switch and connected it to the white wire of the Ford switch. The ground from the Ford switch was t tapped onto the ground wire for the cargo lights. You can connect this to any ground I just chose to keep the same ground as the lights and it was the easiest. I wouldn't normally use a t tap for something critical, but as this was just the cargo light I went ahead with it. I will post more pictures but it looks like I can only get 1 pic per post due to size.

Remove side panel on dash, bottom panel under steering wheel, to access 2 (7mm?) screws that holds the left side switch panel in place. Remove switch panel. All these come off pretty easily.

Remove connector from back of switch. Make t tap to grey wire coming from truck cargo switch.

Route a single wire through firewall into engine bay and underneath to tail light. Cab wire to the switch and connect the ground.

Ford cargo light switch harness. I think it was $34. Didn't get a part# for the switch as it was given to me and I didn't take a picture of the back of it. My friend had ordered it for a 2022 f150 but he had to order for a 2021 as the 22 was too new to be in the system.

Can you meter this wire if it is a 12v or a ground?

If you are connecting the wire from the cargo switch to the Ford switch and then grounding the other wire (ground) on the Ford switch then where does the Ford harness come into play? Is the Ford switch a latching switch or a monetary switch?

It's a ground signal that goes to bcm.
