BCM Pinout Diagram Needed

[amesghali]

Does anyone have access to a BCM connector pinout diagram please?

I was able to locate this one online. Can someone verify if this is correct pin description for connector C2280C, for a Lightning?

I'm trying to make connections for LOCK and UNLOCK at pins 32 and 35 and want to make sure I have it right.

thanks much

I figured it out. The top diagram is the correct pin out. The bottom one is wrong.

Pin 32 is all unlocked
Pin 35 is all locked

When pin numbers are mirrored like that it is because one view is from the male side and the other view is from the female side. If you were to unplug the connector and flip it over toward you, you would get the bottom view.

It's usually small letters but pin 1 should be identified on the connector somewhere to orient you.

If I wanted to add switches with an illumination wire to be connected to the trucks ambient lighting, which pin should it be connected to?

You should search upfitter installation. I realize Ford can change wire colors but on my old truck it was gray/violet violet-gray. That matches pin 13 22 above. Also this thread

Also @JHForman812 might know. He helped many of us with the lighted cupholder mod and one of his harnesses ties into illumination IIRC. The other tied into the LIN bus I think which is not what you want.

That's actually the mod I'm attempting to do! Currently just a little confused/stuck on where to route the wire from the upfitter harness that is labeled "+12v illumination Circuit." I assumed by doing so the upfitter switch lights dim and lighten with the other buttons/indicators.

the lights on the upfitter switches need to tie into the same circuit as your window/lock switches. they have nothing to do with ambient lighting. Let me look through the workshop manual. ill get back to you in a few.

BCM C2280B terminal 45 is the backlighting feature for the overhead console. these are from the bcm of an ICE truck, 45 will already be poplulated cause theres a lot of stuff on that circuit. use a tap or something to tie it in. hope this helps

I edited my post. On my 2010, I picked up illumination from the hazard switch connector. It was violet-gray. Based on John's schematics, they still use that wire color for illumination. My pin 22 reference was bad. I would go with John's advice and tap with a fuse at the BCM.

With this information from you this is what I've updated my planned wiring to. Please let me know if you see any issues with how it's currently set up! I had the illumination and ground connected in other locations, you'll be able to see that still in the mockup.

The way you had it looks just fine, Id go to the closest connection I could get to, instead of running wire all over the place lol

ill go ahead and apologize here, I misread the question. something you gotta understand is illumination(switch back lighting), has NOTHING to do with ambient lighting. its going to most likely be controlled by the dash dimmer function. changing your ambient light setting in sync will only change the ambient lights in the truck(L/R front foot wells, L/R rear foot wells, L/R front door pockets, L/R rear door pockets, and cup holders). all the rest of the lighting in the truck is different than ambient and will not function like ambient does.

Would it just need 12v from any switched power source then? Meaning any fuse in the box would be okay? Being powered in conjunction with the other 12v power wires from pins 1 and 9?

we are talking about the lights in the switches correct? and we are talking about 1/9 on C9120?

if so, then yes these are nothing more than 12v LEDs that just need power/ground nothing more to operate. Ive never paid attention to my switch backlighting in my truck but I think they are on when the truck is on and looking at the diagrams i posted they appear to be on at all times the truck is on.

Well yes 1/9 but also 11 after what you've said about them not dimming with the interior lighting. If they don't dim doesn't pin 11 just need switched 12v power too? Or did I misunderstand something?

Id have to test and see how they function, im not with my truck and wont be near it till the weekend, but the +/- next to your headlight control might dim the switch back lights.

I think im really missing what the question in here. If was adding these aux switches and was trying to power them up I would run pin 11 on C9120 to pin 2 on C930 if i was looking for the shortest route to get the switches lit up. Maybe i need to read back through this thread and see what youre trying to do and what im missing.
