That cable is for the video between the ACM and the screen and is part of the harness. The splitter replaces the cable that goes into the gps module. The gps module will be removed and not reused.

Does anyone know what connects to this receiver? It is behind the amp in the driver's footwell. I don't seem to have anything that plugs into it and can't remember if there was anything in there before.

 

OK!!!! So...the Harness is in, The Unit is in and IT WORKS!!!! Love it. BUT.....a few things to comment on.
1. Whoever said that you would have to "Man Handle" the main harness...Dude that's an understatement. So I beg anyone of you wanting to do this if you have the capabilities and the know-how REMOVE THE DASH!!! I mean this in the strongest meaning of the word. Other wise you will have to Gorilla handle that harness. and Since Ford does not like to deburr their metal you will end up with cuts on your hands, that's a promise.
2. As expected the air temp. is reversed. I will be buying the climate control harness soon to fix that issue. BUT... I am also having a problem with the air selection. I don't know if it is related to the harness or not but air does not come out of the main vents. If i select Front vent and Lower vent air somehow only routes to Lower vents and Windshield vents.
3.It Sounds Great....I assume because I have the Shaker 500 I don't need an Amp. because the sound is perfectly fine. I plugged the unit in and Voila!! music is playing!!!
4. I understand that the GPS module is no longer needed. and its funny because I have one part leftover and the new harness does not have a plug for it. So I ask is the GPS module (PART NUMBER: CR3T 19H464 CB)??? if not what the heck is it???? and Also...it is true I need the GPS splitter to make the GPS work properly right? cause the unit is telling me I'm in Georgia.....and I'm totally not in Georgia.

Other than that it looks and works great Pictures coming soon..

 

It looks like the LED connector...

 

@LEXiiON thanks for the input man. I was afraid that cable would not be there but it turned out just like you said, being part of the main harness.

 

Yeah, it does, but I can't find any cables to plug into it. No clue where it is at. Guess I should check to make sure my footwell lights are working. Also, that is the GPS unit. Mine is currently sitting on the couch.

Currently trying to figure out why my heated seats don't work. Everything (except for the left plug) is hooked up, but when I press either of the heated seat buttons, nothing happens. All of the other controls work. I'm wondering if I do indeed need to flash the ACM for heated seat support. You'll need the GPS splitter otherwise there isn't a cable going to the ACM for it. Are all of the ports on the back of your ACM hooked up?

 

Hey thanks man I was starting to freak out about that little box. As for the GPS I have the one that came with the original set up. The cable with the little brown connector. But I do have one more port behind the ACM that is PINK. Is that where the splitter comes in? Hooking up the brown and pink connectors to the GPS antenna? There is one more cable on the passenger side that is not hooked up. For the life of me I could not find it where it goes it parts of next to the Passanger Airbag cable but it's black and red instead of grey. ..... (You know that's probably it). As far as your heated seats I'm honestly at a loss. Assuming that you have the little side Bezzle wire connected I don't know where it splits to connect to the heated seats. If your original set up had heated seats then it should be plug and play.... That's how mine was

 

Yeah, the pink one is the one you need. There was a picture a number of pages back showing the cable you need. It's basically looks the same as the non-nav one, but has the pink connector with it. (https://themustangsource.com/forums/...9/#post6773321)

I was hoping that the seats would be plug and play and everything, but there is no response whatsoever, the lights don't even come on when I hit them. I figured that even if the ACM didn't know the seats were there, the panel should still light up.

 

Double check that small plug thats on the side of the Bezzle. if the lights are not even tuning on its not getting power. The ACM has nothing to do with the heated seats. You might have something unplugged under the driver side. I would check all your connections again.

Honestly even with the old harness in I plugged the Bezzle and the heated seats worked. and I had no ACM or screen. I can even hear it "click" activating

 

Checked the plug (guess it's called the FCIM plug or something) and it was secure. Tried it on my old bezel just because and it is exhibiting the same behavior now. Looked again for unplugged items and it's just that one I mentioned earlier. Maybe that's it? I have nothing to plug into it though (and the old harness doesn't even have anything for it either from what I can tell). Checked the shop manual and it said that the heated seats are controlled by like four things: The FCIM, the heat relays under the seats, the heater mats, and the thermostats. Seems like the only thing I would have unplugged doing the swap is the FCIM, but it's definitely connected now. The manual says a DTC will be set if the HVAC detects a short in the line and disables the buttons, but there isn't one so that doesn't seem to be it. I'm really at a loss.

 

Check the pins themselves. You may have bent one in the plug.

 

That was certainly something I didn't think about, but it doesn't appear to be the case. Thanks for the suggestion though.

 

Alright!!!! I fixed the vent issue. Totally forgot to plug in the selector motor cable.... (Again I couldn't see it cause I didn't take the dash off) it's is very hidden.
I do have a question tho... There HAS to be a way to reverse the polarity of the climate control harness in order to make the temp controls not be inverted. Instead of having to buy a whole new harness, No??? Any thoughts?

 

I thought that as well, but is was just easier to spend the $30 and get the proper harness. Besides, I will likely get the dual zone before summer anyway.

 

You could have a bent pin in a couple of locations:

C260 - pin 13 or 12
C311 - pin 5, 6, 7, 8 or 9

I can only suggest to look for power using a multimeter. There is nothing to reprogram to get your heated seats. If all connections are good, and everything is plugged in, then the only thing left is the relays are bad, the FCIM is toast, or the climate module is toast. Neither of those is likely, though.

You did get the climate module and switch it out, right? It sits right above the ACM. It should have 2 plugs that you connect to.

 

How many pins are in this? 4? If so, it is connector C215, and it should be plugged in. If it has 2 pins, it is C257 and is for clutch pedal position. But I am certain it is C215. I do not know what circuits it is for, though.

 

I'll see if I can't find those locations.

I did switch out the climate module. Everything about the climate (Auto, dual-zone, etc.) appears to work just fine, it's just the heated seats issue.

Is there a third option?




Thanks again for all your help.

 

Not, that is fine. I double checked. It should only have 3 pins. That is C215. I still don't what the circuits are for, though. Doesn't seem to be related to the heated seats, though.

As for your seats not working, I know this won't sound like a great option, but you may need to go through all plugs one by one. It may be possible you disconnected something you didn't need to and it was never reconnected?

Is the FCIM doing anything? Or just no illumination or heated seats?

What year Mustang is yours?

 

On the connector to the FCIM, power is pin 1 - the brown with red stripe wire. Ground is pin 4 - the black with grey stripe. The other two wires are for communicating with the PCM.

We need someone else to chime in, as I don't know what else could be your problem, assuming everything is connected. Unless C215 has something to do with this.

 

Every button on the control panel is working except for the heated seats so I don't think it's that. The power seats can still move (I doubt they're on the same power as the heater, but just thought I would mention it.) It's a 2013.

I'm pretty sure running through everything and making sure it's plugged in is my only option now. I've pretty much done that already, but I guess I just need to be more thorough.

Edit: I was going to run through the Pinpoint Test F from the shop manual, but apparently my logger doesn't support the PID for it. Doubtful that a random one from AutoZone is going to either so running there isn't going to help.
