I do not. Just follow the wire color in your pigtail diagram, look for the bus wires behind the obd2 port they are the colors listed

 

Just get another job........
Or start a Go Fund Me Page!

 

Oh, NOW you tell me! LOL - If you get it working, I'll just have to spring for a new CCM.

 

Lol, it was your post that got me thinking "hmm...I should probably mention this..."

 

Awesome. Hope just firmware will do the trick.

Anxiously awaiting...

 

It's official - I'm in the club! Installed and activated ACC today on my 2017 Lariat 3.5 EcoBoost 502A with tech package, and it works like a champ! Love this option!

Let me say thank you to all of you who contributed to making this mod happen and then documenting the process so others could follow! And special thanks to EcoBoost Morgan for working out the kinks early on and to Livnitup for all of his work on FORScan and getting the functionality for FORScan to be able to calibrate the CCM. What a simple and easy process - and I didn't have to go to the dealership!

For those of you who are about to embark on this project, keep in mind that there are five processes here; bumper harness and CCM/sensor installation, HUD installation, steering wheel control switch installation, module programming with FORScan, and sensor calibration with FORScan. Get comfortable with FORScan before jumping into this. A couple of simple mods via FORScan beforehand will give you valuable experience. And make sure you're running at least v 2.3.12 so that you have the sensor calibration function available.

Though the installation and programming are well documented in this thread, I wanted to add a couple of things that would have helped me understand the nuances of this install a bit better. Just a few unexpected odd-and-ends that I ran into along the way.

1. Bumper wiring harness - The FL3Z-15K867-B is the correct harness for the CCM on the 3.5 EcoBoost; the FL3Z-15K867-E is the harness without the CCM. Order the B harness to install ACC.
2. I ordered my parts from Tasca. I didn't mess around with the parts they were 'iffy' on; I ordered those parts from eBay. Everything arrived within a two-week period.
3. The only wire harness plugs you have to remove before removing the bumper are the fog lights and the harness retainer pins closest to the fog lights. The other parts of the harness will stay with the front of the truck for easy removal once the bumper is removed.
4. Using a pnuematic impact driver and a 21mm impact socket made taking and replacing the bumper bolts a piece of cake. Be sure to follow-up with proper torque.
5. The two upper bolts for the sensor mounting bracket face to the rear of the bumper; the bracket overlaps to the rear of the bumper. Place the bolt stop nuts and the scrivets first, then insert and tighten the bolts.
6. I couldn't find a 5.5 e-torx socket, but found that a 4mm hex socket worked well to tighten the sensor studs. Take your time, seat it a deeply as possible, and don't twist too quickly.
7. Don't mount the sensor module on the bracket in the bumper until the bumper is back in place on the truck and torqued into position.
8. When removing the airbag/horn assembly, I sank the shafts of the 3mm hex wrenches 3 inches into the holes on the side of the steering wheel before they engaged anything. I was beginning to think that they were going to stick out the other side!
9. I could not figure out how to release the horn wire connector (the easily broken connector on the side of the steering wheel trim), which meant I had to remove the switch while wrestling with the partially attached airbag/horn assembly. That made changing the steering wheel switch a PITA.
10. In FORScan, I made back-up configuration files of my modules after adding the CCM module, since that is now my 'original' configuration.
11. After initiating the sensor calibration procedure, I started driving and noticed that the calibration warning kept going off and on. I think that was because I was in traffic and couldn't keep a consistent speed. Once I got on the freeway, it seemed to clear permanently and I was able to turn the ACC on and it worked perfectly.

Thanks again, everybody!

I'd love to do this if possible on my '15 Lariat 500a without going wiring crazy. I've got a 3.5 EB. My harness connector for the fogs and shutters is in the exact place described. I've also got pushbutton start and the HUD connector in the dash. I've done LOTS of Forscan mods, so that is a no brainier. Please let me know. Thanks!

 

Not sure what is necessary for the 500A trim. Though the -B bumper harness is correct, I don't know if the other stuff needed for ACC is on the truck. I know there have been discussions on various trim levels in this thread (301A, 501A, 702A, etc.), but I don't recall a 500A discussion. However, doing a quick search in this thread may give some useful results.

So, I've done some more poking around my truck: It appears I have all the fuses in place. These include (under the hood):
- Fuse 11 Automatic brake system motor
- Fuse 61 BCM Automatic Brake system valves
- Fuse 110 4x4 run/start, Adaptive Cruise Control

I also have the pigtail for the HUD in the dash and an 8" cluster.

I'm looking for the pinout/wire color coding on the truck side of the harness that the FL3Z-15k857 harness plugs into. Does anybody have that? There appear to be 10 wires coming into the truck side plug that the FL3Z-15k857 plugs harness main connector plugs into.

If all the wires are there on the truck plug, is there anything else anybody thinks I'd need?

Thanks!

 

Update: I don't have stop & go working yet but I'm a step closer. I hit a minor snag and reached out to a buddy in Australia for some pointers on resolving the snag and will continue the work this week...
