Smart junction box wiring diagram and pinouts needed?

Hello, we do have access to the connector diagrams and pinouts, it looks like there are 8 connectors for this module, labelled as a Smart Junction box, but it's really a BCM. Going through the diagrams, this thing looks to control much of the vehicle and communicates on the medium speed CAN bus network. I don't see a part number listed anywhere, even just doing some random searches for used modules, I haven't seen your particular part number yet. But what type of issue are you having with this module? The list of DTCs is a mile long because they are all listed per system. Or are you having a No Communication with the module? I'll get the connector diagrams ready for you, but if it's a certain specific issue maybe we can help you figure out what is going on. Since this looks to have the security system integrated into it, programming can get complicated sometimes. But let's start with what issue is going on.

These are all 8 connectors, diagrams (1,2connector A) go together- (3,4connector B)- (5,6connector C)- (7,8connector D)- (9,10connector E)- (11,12connector F)- (13connector G) - (14,15connector H)

There is a diagnostic Flow Chart if there the SJB has no communication with a scan tool.

I'm having a bunch of issues with everything that runs through there, blinkers, ECU, A/C clutch, pretty much all the accessories and the ECU because they run through there, I've also got to get the wiring harness that attaches to the front, everything goes wonky. If I wiggle those wires, I had to zip tie pressure on the wires to get home the other day because it turned off power to the ECU.

Okay, I posted the connectors on my last post, so refresh this page and they are there. If you're having to put pressure on the connectors to get things to function, you should check the pin fitment and make sure there are no loose pins in the connectors. If a wiggle test is showing the issue is right at the connectors. Sounds like you're dealing with either pin fitment issues or cracked solder joints on the inside of the board where the connectors are. If you take the SJB out of its case and inspect the solder joints with a magnifying glass for the connector pins, look around on the back side where the pins are soldered, and check that there are no cracks around the joint. Here is a picture of how the joints crack. Or you might find corrosion on the board. But cracks like this can be repaired.

Yeah, I didn't see any correct joints. I'm going to look them over again with a bigger magnifying glass, but I'm just going to buy a new harness out of a junkyard if they're all the same. Because I'm sure some of them are broken in the wiring with the steep angles they take, even holding the connector on there and the wire tight. If I move the wire some, I know at least one of them to the left blinker is broke in the wire, not at the connector.

Being in that right kick panel, also look for any water intrusion, corrosion inside the connectors as well. This module controls so many components, I can see moisture getting into this location, I've seen plenty of fuse panels in the right or left kick panels full of corrosion. All those C2280 are the SJB connectors. It's difficult if the fault is not actually with the module, it sounds like you're dealing more with a harness issue. Auto parts stores carry terminal cleaning spray you can try that also in the connectors. Have you found any of the wiring to the module with corrosion inside the wire insulation?

Yeah, I've already cleaned it twice and cleaning. It cleared up some of it but some of it is actually in the harness.

Are the wiring harnesses the same for all of the '07 Mustangs? Like the one for the V6 4.0 and the one for the 4.6 with regards to just the harnesses that touch the sjb?

Yeah, wire corrosion can grow into the insulation and up the copper wiring pretty far. I have seen it happen even where there were no cuts in the insulation too. I will go over the harness connectors and see if they are any different. I did a search for the module and in some of them it looked like the same module was used from 2007 and 2008 but I would have to check the part number and I didn't find a part number in service info on All Data, but I'll keep looking. The one thing I'm not sure about is the security system, in some cases when replacing a module with security involved the module needed to be brand new with no preprogrammed VIN number to it. So, it varies from brand to brand. I can post on an expert forum about it and see if any other technicians know. I'm sure some factory Ford techs will know right away if it does. Or if a used module can be installed. Do you have any scan tools? And have you checked out FORScan? Here's a link to the Ford page.
It can be used with a ELM327 OBD2 adapter and I believe the software is free. It's a good option to have if other scan tools sometimes don't work in certain situations.

And so far, the 4.0L and the 4.6L are exactly the same Body Control Module, all the same connectors and pinouts. I'll check the 5.4L as well.

Thank you very much. I appreciate it, I have Forscan and IDS, I know how to reprogram them. I was just trying to make sure that pin outs were the same, I figured they were. It's hard to check the solder joints on the back of this thing with that gel coating they have, so I'm just going to have to scrape it all off.

I gotcha, yeah, I've had to deal with that gel coating before too, I try to repair modules when I can, saves people a lot of money. So, the aftermarket diagrams for the 2007 4.0, 4.6, 5.4 all look exactly the same, so does the 2008 4.6L. I didn't go through the OEM diagrams, and it still doesn't give me any part number for the SJB or Body Control Module. But it's listed under BCM as well as SJB. I'm surprised that they would have one module do so much, it makes diagnosing the thing really difficult. But I would verify every wire in each connector before trying to find another one. I know that will take a long time, but you don't want to spend the time programming another one, just to find that it's a wiring issue. It's supposed to set codes for each specific system it controls. There's sections of DTCs per system. So, you should be able to communicate with it and pull codes, that way you can narrow down which wires and connectors to go after for further inspection. Whatever will cut down the diagnostic time with this thing will help.
Here's the network topology just in case you need it.
Do you have comms with the SJB?
