Work at Braidwood, live in Yorkville kinda.. Yup, see everything else.
So, disconnected and pulled CCM back off, looks like I should have voltage between pin 10 and pin 4 on its harness connection (truck "on" but not running.... assume that should give me something) now looking for main connector diagram to see if I have continuity on new harness and voltage on existing pin for ccm

I missed your post that you already made all the other changes. I am actually headed to the kendall county fairgrounds in yorkville tomorrow for a gun show. If it wasn't so friggin cold out I would be tempted to either pull my ccm and try it in yours or pull yours and try it in mine. Now that I typed that I realize I probably wouldn't have to pull it if we could get away with unplugging mine with it still mounted and just plug yours in to read the module. It would at least eliminate the module as the problem and narrow it to wiring for you.

Where do I go to access service info? isn't there a 3 day or month thing?

There's both: https://www.motorcraftservice.com/Purchase/ViewProduct

If you need a certain wiring/connector diagram I can post it for free if you tell me what you need.

Main connector thats by the right headlight that connects to fogs/shutters/ccm, need both sides of it.
looking at the downstream side the power to ccm is yel/blk, the corresponding pin on the upstream connector is empty, I need to see where power is coming from (fuse 110 I think) and where it's supposed to be on the connector.
appreciate it immensely!!
trying to attach pictures...

So..... the truck is 2wd, it looks like Fuse 110 goes to the CCM AND the TCCM, is it possible that since the truck came with neither that there is a different harness for 2wd w/o ACC? WTF..

Looks like it's C134 and the power circuit is CBBB0

OK, did some modifications to some wiring, now I see CCM, tried the calibration but what I do not see is cruise control on the screen, it won't toggle on.
any ideas?

Add me to the list of complete!!
Thanks to Livnitup for some help and to all the ones who came before that added a little bit of insight.
I have a 2017 Lariat 502A 2.7EB 2wd Scab and I don't know if it's an oddity of my special order truck or someone screwing up but I was missing the power and ground on the truck side of connector C134 (what new harness plugs into), so big thanks also to the 302A guys for coming up with the new power scheme.

Hey guys. This is a great thread and a terrific forum.
I received my parts the other day. Inventoried them today and they didn’t send me the two lower mounting studs. So I can’t get started in earnest yet. Sad face.
Ive got a 2015 Lariat 501a with a 5.0L engine. It has the plug under the dash for the collision alert HUD. Already plugged that in and it lights up when I start the car.
Anyway, what I don’t know is whether I have power going to the CCM at the harness connector, given my trim level. I’d like to test that by plugging in the new harness and the ACC sensor and looking in FORScan. Do I need to do anything other than plug it into the harness (both ends), cycle the ignition and open FORScan to get FORScan to at least “see” the CCM in the list of modules?
Thanks in advance, Brian
