Do you guys remember which wires you spliced into for the diagnostic port? The wire colors are different, so I spliced into the ones in the picture and my acm would turn on and off. The door chimes stopped working too. So I unhooked them for now.

So i ran the 2 wires from the switches down to the hmi plug. Cut the 2 that are to go to pin 4 and 6 and spliced them in. I double checked the wires. And everything seems good. I'm not sure why they are not working. Unless it's because the sync module is fro a 13? But I would think the wires are still the same.
It's possible that the '13 has different steering wheel buttons, and therefore is wired differently--have you looked at a wiring diagram for a '13? The sync module I'm using now is from a '12 and works fine, FWIW.
As for the mike, on my car I didn't spend much time with the "kit" mike, but it didn't work when I tested it. The "factory" mike on the rearview mirror worked fine using the same wires. I suppose it's possible they're electrically different somehow.

Not sure what you mean by "pin 4 and pin 6"--thought that the HMI connector only had 4 pins. Did you check the resistance on the new wires at the HMI end as you push the steering wheel buttons? It should change as listed in hdvalente's old post.

Pin 4 and 6 coming out of the steering wheel then down to the hmi plug. I will test the resistance and see if it's any different. I will have to find the wiring diagram for the mic in the head liner and see if how it wires up. When looking at the mic from the 09 sync kit it was completely different than the headliner mic. I am also going to test a different acm that i know came out of a sync car and see if I get anything.

Ok. So that would narrow it down to the mic or the wiring is different for the 13. I will mess with the mic tomorrow and see if I can get it to work

Made some head way. I got the mic to work. The 13 sync module is a bit different that the 12s. I had to re pin the plug for sync at pin 18 for mic in+ and switch pin 5 to mic in -. Still no buttons working though. The pins are the same. So it maybe a resistance issue. Or still a wire different somewhere.

After a bit of research, I found on the ford parts site the buttons from 10-12 share the same motorcraft part numbers. The 13-14s are different. I tested the resistance of my switches and they are the same as you guys posted. On the diagrams for the 13 the resistance is way different. I'm guessing it is the switch that is causing the issue. I have a 13 switch on the way and will test it once i get it.
