I have a 2022 F-350 Diesel. I am looking for a particular wire coming out of the BCM. I am installing a GJ Motorsports 3rd brake light. According to someone there, they said it is the same as the 2015-2018 F-150 reverse wire (C2280C, Pin #11, GN-BN wire).I am hoping someone could actually show me a diagram page for a brand new super duty.
Thanks in advance.
PayPal $20 to whomever gives me an answer that checks out with a multimeter.
I do believe @TB250 has the winning answer, well I hope. I will pull the multimeter out tomorrow or Wednesday. Its supposed to rain non-stop till late tomorrow.
I'm leaning towards the first post (C2280C, Pin 11) as well since you're looking for the reverse/backup signal (not stop). Mine 2017-19 manual has the same.
I'm not familiar with the GJ Motorsports 3rd brake light, But there should be a loose designate and label 3rd bake light wire just in front of the spear tire under truck.
I used it on 2020 super duty for truck cap 3rd brake light. Not sure if that's what your looking for.
@TB250 I wont be tapping into the BCM. But I verified with the manufacture and he agrees with your assumption so I owe $20. Let me know how to send you that on PayPal. But tagging onto what @jim7044 said, the distributor said I can vampire tap into the reverse wire that is under the dash connected to my trailer brake controller. I looked at my 7 pin on the back of the truck and I know what color that wire is for reverse but I would like to verify through ford literature of what they used for colors in the dash. Another $20 is up for grabs.
I will add about the Reverse light signal at the rear trailer/camper adapter. The signal leaves the BCM, goes to the engine compartment BJB and then goes to the rear adapter.
@h20camper well **** thanks for the info. The distributor might of been misinformed about the TBC. They did say there is a wire under the driver side dash that you can tap into for the reverse light. I am trying to avoid tapping into the BCM wiring. I just dont feel great about tapping into the BCM wiring. Not that tapping into any factory wiring is great.
@h20camper yeah I am trying to keep the wire in the cab. I have it run to the passenger side kick panel because I had to hook my weboost and other lights to the upfitter pass through wires.

You don't owe me anything. Pay it forward to the next guy looking for help.
