Hi JonsF150,
On your wiring question if your truck is not a high option level one like KR2019 then you are probably missing all four wires needed to power and communicate
between the IMPA and CCM. I have a 2019 Lariat with 501A package and it did not have the four wires needed. You will need to make a harness with the four
wires. A twisted pair, hot and ground starting at the C9224 connector and going thru the firewall to the C134 connector using 22ga. wire.
Thank you for the reply starliner57. Looking at the C134 plug I got lucky I guess. I have all wires except pin 5. Now I know I don't have the CAMBUS wires to the IPMA to the CCM but am hoping that I have power and ground already ran and since the CAMBUS wires are at C134 I am hoping they will also be inside the firewall already in C265. If that is the case do you think it would work out okay or do I just need to go ahead and run them all the way to the C134 connector. I have never done a job that I had to work with wiring for the CAMBUS so this is all new to me.
I also have the 502A. The C9224 is the connector at the IPMA it is green in color and you are looking for PINS 3 and 11. Those are the CAMBUS network to the CCM module.
C134 is on top of the passenger side frame rail just behind the front bumper and as you can see with the PDF what pins you might need.
Not the best picture but all I have at the moment.
Hopefully that can help you out some.
That was exactly what I needed. C9224 seems good to go as I have every pin except the 3 blanks but I will need to check C134 more closely as the pic below was the best I could get while at work dressed in a white dress shirt. .
JonsF150 looks like your C134 connector is good to go on the body side of the connector you can double check them when you
plug in the new bumper harness for the CCM. On the C9224 connector looks like you are missing the canbus wires 3 and 11.
Use 22ga wire and they must be a twisted pair if you can find C265 and varify the wires are there on one side of the connector
(should be 15 and 16) then you can pin there.
Well I got my wiring ran. First time for messing with terminating factory connections. I don't think it should be as hard as it was but I'm sure I'll get better. The crapy part of this whole things Is I've got everything ready to go in and program but they forgot my studs for the CCM modulle and will not be able to mail them until Monday. Hopefully they come quick but I did hook up the CCM and ran a test on it. I can communicate with it so I at least know all of my wiring is good to go now.
If any one else is doing this on a 2020 with a 3.5L eco and LED fog lamps the bumper harness you will need is LL3T-15K867-FA
Hopefully one my studs come in programming goes easy and I'll have ACC with stop and go functionality by the end of the week.
Thank you s_vares for the reply. Look like you got really lucky. I was only half that fortunate.
fordpiper you ROCK!! You were correct I did mean C9224. Thank you so much for the detailed part numbers! That helped me out a ton. If you have time could you explain how you found those part numbers. I have the service manual for my truck but never saw any information on the pins themselves, just the connectors and not all of them have service part numbers.
I have the hard print version of the electrical wiring for my F150 and the electronic version of the workshop PDF that you can buy which is some person in another county just going online to motorcraft.com and printing page by page. However I have found this isn't everything because I paid for the expanded version (or whatever it was called) but it does not include the terminal pin references per connector. Sadly my hard print doesn't either. Good news is you can spend some money and pay for 72 hour access and download the connectors terminal pin references for the connectors you are interested in. This is what I did and then spend a lot of time cross-referencing connectors and pins to Molex and TE so I could order everything I need to do all the mods I have planned.
No dice. Tried it and still getting the "pre collision assist not available" on the cluster and the 2 codes (I will post pictures of)
C1A67:08-6C
&
U0405:64-AF
I have installed the new proper switch, checked all the wiring, checked all the as built, and I keep getting these codes after clearing them.
Cruise and Collison inop.
I installed H1BZ-9E731-F senor and KL3Z-2C219-E ABS module. I have the proper IPMA according to for parts and this thread.
I'm totally at a loss!! Any other ideas?
One thing I did notice is some modules in the truck have more lines than the as built data. What's up with that?
See picture for reference. Last 2 lines seem like mystery lines.

I’m newer to all this but did you have to run new wires too the CCM from the IPMA or were they already there?
Have you done a network test to the CCM? ( I just saw that you did run the network test and it passed)
JonsF150 I noticed you listed part number H1BZ-9E731-F as the CCM you purchased. KR2019 listed part number JX7Z-9E731-F
I ordered the JX7Z number for my truck I wonder if you have the incorrect CCM
