Default Wiring diagrams needed

Would someone that has access to 2021 3.5 eco f150 wiring diagrams mind sharing the diagrams related to the center high amount stop lamp camera?

thank you

Not sure what this is from but but the F150 has three wires for the brake light and I think six for the camera. In this drawing, it appears there are only two wires?

Nothing relevant, are you seeing something I’m not?

This is specific to a 2021 F150. If you look at pdf #2 in the top right corner, it says the model year and vehicle these pertain to. This is directly from Ford's PTS dealer website.

Thank you, I appreciate you sharing the files but the attachment is not for the brake light with a camera.

If anyone else has access to the wiring diagram, can you please

This is from the 2022 Workshop Manual (on CDROM from Helm, Inc.) but likely applies.

Note that on CHMSL INCLUDING WITH 360 CAM.pdf there are 3 different possible connectors shown
  • C904 for incandescent
  • C9030 for LED
  • C9125 for LED with 360 camera
I've also attached the connector detail for C9125 for LED with 360 camera which shows pin assignments and wire function

Hope that helps, have fun!

EDIT TO ADD CHMSL CAM WIRING.pdf (took me a while to find that one, turns out everything relating to cams is buried in the "Parking Aids" section of the WSM wiring diagrams (!), this shows the complete circuits for the CHMSL cam wires in connector C9125)

thank you! C9125 is the connector I was seeing.

How do you guys have access to the wiring diagrams? Is it through a subscription? Or are they posted somewhere? I’d love to be able to find these myself, but just come up empty handed or images I can’t make anything out on.

thanks again

Like every good tool in my workshop, I paid for it.

You can access the same thing, ~$27 for 72Hr subscription, here

I have a post on the F150Gen14 forum about other sources, none of them free, none as good as the above, IMO, but can't link at the moment because that site is down right now.
