Where is connector C265?

[TeeJayHoward]

I can see the general area where it's supposed to be, but there's an awful lot of connectors here... Which one is C265?

This is in the right spot, and has the right number of pins and all... But WAY wrong colors on the wires. Not a single wire color matches up. Please tell me it's not the one I'm looking for.

Do I have to take apart more of the dash to get to C265? Anyone got a photo of what it's supposed to look like?

That appears to be it -- verify wire coloring / placement. Remove the TCCM for easier access

Damn. I didn't want to hear that. The manual shows very different colors for each wire. For example, the Brown-Green one in the top-left of my picture? That's pin 25 - supposed to be Violet-Red. In fact, the only Brown-Green wire on this connector is supposed to be pin 59, which is 22AWG. It's this way both in the Helm manual and the .pdf workshop manual floating around the 'net.

Did Ford just give up and use whatever wire was laying around, or am I misreading something?

(Also, do you happen to know which sockets/terminals/pins/<insert term here> to buy for the female side of the connector - 16AWG?)

edit: This guy's connector looks like mine. Are both of my manuals wrong?

You're wanting seat stuff? Open it up and take pics of the BCMC side like this

Take thorough pics trying to get things in focus.

Yes, it's very possible that ford changed some things. If you have the fuses under-hood for what you're wanting, you're going to have to find the pins. Not hard. If you screw it up you'll only melt the connector.

Hah! Yeah, right. I'd have to remove the BCM just to get my oversized phone at a decent angle. I really need to pick up a fiber scope one of these days. I did take a bunch of pics when I had it apart a few hours back using a mirror, and it looks like the only 14AWG connector I'm missing is pin 22 (Fuse 38), which makes since - it's not in my fuse box either. The little 22AWG guys shouldn't matter. (right?)

Spoiler: Terrible images

edit: Stealing QuestionableStandard's image, since the pins I care about are identical:

Mirror fuggs things up for remote diag, nuh uh. The TCCM is that box on the floor in the way, unplug and remove (10mm). If the connector is attached to something and won't move for images, pull it off whatever it is on.

Here's how the numbers correspond to the C265 pinout (using the BCMC's side as reference, C265 is what you unplugged from this connector). ASSUME NOTHING. Print out C265 on a large piece of paper, take your volt meter and carefully check for 12v on the center group of pins, 1 at a time (lines drawn between what I'm calling the center pins, not to be confused with the edge pins, don't short 2 pins together). Take your big printout and simply put a + to each pin with 12v present using your volt meter.

Let's assume that Ford just changed their wiring colors and didn't update the documentation.
We'll also assume Ford ran a wire from Fuse 31 to C265-21 (Male side).

I need to run a wire from C265-21 (Female side) to my passenger seat in order to provide it with power. The female side of my connector does NOT have a socket/terminal in it, even though the male side does. What is the part number of the pin/socket I should be using?

Again, assume nothing. I believe the pin locations for the seats to be similar so what you do is check for voltage on the pins. THEN, go pull the fuses for the circuits you think you're after. Check for voltage again to verify you have the proper circuit. DO NOT ASSUME, you can melt C265, I've seen it done already.

You may have the fuse for the DSM too, pin 22 if you're interested in heated / cooled seat upgrade with DSM. Also, pin 38 is for snow plow / rear heated seats. It's a 'free' 20a keyed circuit for fuse 19/48 you can use for future accessories. I suggest to pin up a few feet or so of properly sized wire for said future circuits and label them accordingly. The seats / DSM is always powered, pin 38 should only have voltage with key on.

"But I don't have snow plow or rear seats. I'm sure it..."

Nope, it's there. Awesome! I might steal that circuit for heated seats instead of tying in to the driver's seat power circuit like I was going to. Still gonna need terminals. Advice?

No, use the DSM circuit for that and use 12ga wire. It's a 40a fuse, but always on. What seats do you have?

Tremor seats.

401 or 402? Got a pic of them?

Dunno. I think it's 402. (Posted a pic in the previous post) Heated/cooled w/ DSM, adjustable tilt headrests. Power recline/forward/back, inflatable lumbar.

Okay, well in that case you need to follow that thread in regards to getting them working including pulling the wires to the connectors properly. The driver's seat ends up powering the heaters of both seats as well as the fans. From the melted C265 connector, it was discovered the DSM combines the power from both the driver's seat wire and the DSM wire for its functions. Highlighted is the factory wiring gauge for each pin. Pin 20 is on a 40a fuse because in non-DSM trucks, it also runs to the HVAC unit to power the heaters in the seats. In seats with a DSM, the DSM's wire needs to be run so that it doesn't overload the 14ga single wire from the seat.

 

[TeeJayHoward]

I wonder why the Helm manual shows different numbers from the Workshop manual .pdf? Did the wire gauge change depending on options? It doesn't matter to me - I don't have Fuse38 in my BCMC, so I can't use pin 22 regardless.
