This is going to be a quick basis of how to install a rear view camera in a 2013 Focus ST with APIM Programming. I was going to send out my APIM to have it flashed, but being that I plan to upgrade to Sync 3 shortly I figured I'd try to figure out the APIM.

Install Backup camera in place of trunk latch handle
Take wireless rear receiver and tap red power wire into left taillight green and brown wire which is accessible in rear left hand side of car.
In the same harness the black wire is the ground so connect this with your black wire of the wireless receiver.
Now remove ford Touch from front (make sure to use tape on the leather sun visor over the myford touch. If you remove the lcd without taping, the top ears of the screen will scratch the leather when you pull it out). Take female RCA cable and keep only about 6 inches of wire length. take the insulated wire and solder it to a 6 inch strand of 22 awg wire. Do the same to the non insulated wire also. Now crimp on the end of the 22 awg wire the TE terminals mentioned above in the parts list. These can be a real pain to crimp if you don't have a crimping tool for them. You can always attempt to crimp them and then add some solder. The terminals are a real tight fit into the harness connector so you might be trying this a few times. With the TE connector ends now installed you can slide them into the my ford touch harness connector. Pin 14 should be the insulated wire from the RCA end (Center male pin) in the myford touch harness and pin 15 is the non insulated RCA end (outside part of terminal). Now the front wireless receiver RCA end can plug into the female end you just wired up to the myford touch. The power and ground wires on the front wireless module now need to be fed power. I tapped my radar detector add a circuit which is circuit 85 (could be mistaken) which is the fuse box behind the glove box.
Now to the main part which I can contribute here. Everything else has somewhat been mentioned before. The APIM behind the myford touch needs to be flashed to allow the rear camera function. To do this I recommend the OBDLINK MX as that's what I have and it works flawlessly. Now Download forscan below and it has to be the computer version. You'll need to join the forum and ask for the Free Extended license which unlocks the APIM feature.

Now you'll need to access the APIM menu and change the digit shown in red to the number 3. Flash

After Complete install and APIM flash you should see this when you put your car into reverse. The Rear camera feature comes on almost instantly and it works flawlessly.

I'll see about maybe adding some more pics and stuff, but I just did the camera install along with adding an MFactory LSD to my trans so it's been a very busy 4 days. I'm exhausted but figured I'd help a few of you out.
