All right boys and girls, Just wanted to start a thread about my venture into installing the OEM SYNC 2 navigation system into my 15 XL LWB cargo van.... This is what I started with... With a dremel and some bent pieces of metal.... and this is where I am as of right now... Next on.... Wiring! To be continued....

I added some nice LED lights to the cargo area of my SWB 2016 wagon. The lights have an OEM look and provide just enough light to illuminate the cargo area. The lights are mfg by Brand Motion http://www.brandmotion.com/oem-integration/led-lighting/loftlite-led-interior-lighting-kit.html The total lumens from the 4 lights is probably around 90-100. I tapped into the wiring for the side mounted cargo lights. The lights turn on and off with the doors. They dim as the interior lights turn off like the stock incandescent lamps. Each light has a function where separate power can be wired to the light to turn it on by pushing the center of the lamp. Unfortunately this won't work in the TC because the TC dims the lights and turns them off by raising the negative supply to the lamps from 0 volts to +12 volts. So when the lights are off both leads are at +12V. The "push-on" function won't work because when the lamps are off there is no negative supply to the lamp. This is not a problem for me because I would never be in a position to turn the lights on while I am driving. If you wanted them to be reading lights for passengers it would not work. The installation is relatively easy. You have to carefully pull down the headliner just enough to access the back side and cut 4 holes. The insulation on the headliner has to be shaved away so the bezel can snap onto the lamp (use an xacto knife and cut at a 45 deg angle from the bottom of the hole). You will also need to temporarily wedge something between the front lamp housing and the roof so you can push the bezel on. I cut a short piece of PVC pipe and stuck it on a long rod. You remove the wedge once the unit is snapped into place.

Hope you guys dig it... Just my slight build on my 2015 TC.

Backup camera works great. Backup camera goes directly into the APIM harness at pins 14 and 15. I just clipped the backup camera's RCA jack off and terminated it with the mating pins for the APIM connector. I then went in with forscan to change the value of A128 to a A328 at 7D0-01-01 to activate the backup camera. I'm not sure what you mean by "tipping your hand" but the canbus infrastructure should be the same if the vehicle model could be factory optioned with the SYNC2 / SYNC3 systems. The 3 canbus interfaces are of the same speeds between all the ford vehicles I've studied. Sure, there may be different modules that may be missing or present dependent on options. I guess worst case scenario, I could sniff the canbus packets on another vehicleand resequence them to fake the 911 assist problem or figure out how to deactivate it within the APIM. I haven't had the time to do it yet but I believe reprogramming the restraint module should clear my 911 assist issue. Will confirm in a few days when I get back to the vehicle.

Quick update.... finally got some decent weather to work on this over the weekend. System powers on and plays for audio for a few seconds. Sadly, it powers down with a battery savings message. I can power it back and it repeats itself. I'm not really sure if I'm missing anything obvious. I checked all my connections 3 times but I haven't found anything. I powered the APIM and the GPSM off fuse F67 just like the OEM system. The ACM and the front buttons are powered off F79 also like the OEM diagram. I found a strange discrepency in the wiring diagram and the actual wire color connected to my mechless ACM with regards to pins 3 and 5. Kind of odd but I tried matching up to how the SYNC 2 system is defined. Haven't found anything else more obvious yet. Next step is to see if the BCM or IPC needs any coding to enable anything. Possible things I can think of is needing delayed accessory power enabled or if I need to enable the canbus on the IPC (pins were not populated on the IPC harness). If anyone has any ideas or suggestions, I'm all ears.
