Adding Co-Pilot Assist 2.0 with Forscan?

[KTM753]

I opened access to everyone. Let me know if you can't see it.

Good point. I don't know how to make a harness... Buying the harness might make sense so I can add 360cam or parking sensors later. Right?

I got access no problem. Thanks. Good comprehensive list in organized manner, nice to have.

If you plan to add parking sensors and/or 360 cams I think it makes a lot of sense to buy the OEM Ford harness. This will make the 4 wire harness for CCM longer as the bumper harness starts on passenger front of truck. But it's not much farther. You will need the necessary wires from dash controllers for 360 cams and parking sensors too. I am not sure off the top of my head if they come from IPMA too? Or elsewhere. Lots of scattered info in this thread and the 360 camera thread. It's a good one also. Some crossover with this one.

I requested access to your Drive via the link.

I agree about 360 cams and parking sensors needing their own harnesses. If you are adding them too, my opinion is to use the OEM bumper harness and just add the wires from the cab controllers to that bumper harness starting point. Unless you really like making harnesses...

Keep in mind that 2 of the 4 wires in the new CCM harness you need to build are Can-bus (Can high and Can low). Those two wires need twisted together to communicate properly. The other two wires are power and ground, no special requirements.

Do you have the part number for the front bumper wiring harness? I tried looking for it in the thread, but it's buried.

There's some conflicting info on whether or not the Can-Bus wires need to be twisted. I know someone mentioned just using a 4 connector jacketed cable. Has anyone who did not twist the wires had any issues so far?

Are you positive your truck isn't pre wired from the IPMA to the bumper connector? Most Lariats are but I know 22s are weird. After just getting my new truck hooked up the other night, for some just running a new harness might be easiest route and since you have a ecoboost you'll need to remove the front bumper to get everything mounted. I think the factory wire is 20 or even 22 gauge wire, so anything bigger will be just fine and you shouldn't worry about twisting the wire as it isn't twisted in any of the factory harnessing from what I can tell.

Looks like I'll need the NA. I will update the Google Doc.

Can bus spec is 1 twist every 25mm (~ 1 inch). Is it he can't see enough wire length under the conduit to see how much twist there is? Or there isn't any twist?

Do you want to chance it and have issues later? Maybe have to do it twice? Or do it correctly the first time?

The communication between the CCM and IPMA literally prevents a collision between yourself and another vehicle if you don't intervene yourself. I would want the correct wiring setup that carries those messages at a rate of 2 MB/second to have the best chance to do it's intended purpose.

What's the twists purpose? "CAN bus cable consists of a pair of wires known as CAN high and CAN low (indicating high and low speed, respectively). Both wires are twisted tightly together to ensure that electromagnetic interference affects the signal in both wires uniformly, limiting errors." It's so if there is interference, both wires have the same interference and thus the CAN signal difference (High vs Low) is unchanged.

Thank you for the explanation. I had no clue why they needed to be twisted. The question I should have asked was: Can someone describe how to make this harness to someone who literally found out what Can Bus was 3 hours ago? I understand the pinning/connectors. Are there any requirements for the other 2 wires? Do the Can wires need to be shielded from the others?

 

[JLJ742]

We will havea complete plug and play harness to add the CCM soon. I went ahead and made one so the guys that dont have the wiring can add the CCM.

It will be a plug and play at the IPMA . No pinning or anything.

I know this is an older post but wanted to check if these were still available. I looked on the website but didn't see them.

Nope. Just need two 22 gauge wires twisted every inch and then two more 22 gauge wires for power and ground. All four can be put in the same conduit or tape. No special requirements for the wire.

Great. Thank you!

From the responses I received, no. We can wire directly from the IPMA to the CCM with the terminal kit and CCM connector. See my post 941.

I apologize in advance for my questions, trying to piece this together. This is new to me. I do have a Comma 2 on my Toyota but this is a different level of install for me. I'm picking up my 21 F150 XL soon so I have not checked the wiring.

I'm assuming mine is not prewired (base level XL Reg Cab) and I am just adding ACC and LC for the Comma 3x. It does have the LKAS button and camera.

Trying to see if I'm understanding my process correctly:

-Remove Bumper
-Attach CCM to back of bumper
-CCM connector is wired with four wires total, two twisted wires for can bus info and a wire for power and a wire for ground need to be inserted into connector
-Attach CCM to CCM Connecter
-These wires are fed into the driver side up to the IPMA via Firewall
-??Not sure how to connect directly to IPMA?? Terminal kit into wire harness into IPMA(same wire harness that the comma 3x will eventually split off from)?
-Level CCM (if Needed)
-detach battery (wait 30 mins)
-add steering wheel button
-reattach power
-Open Forscan
-Save current profile (take Pictures)
-Change relevant values except CCM values
-Rescan find CCM (do not load new profile)
-Change CCM Values
-Calibrate (drive)
-unplug forscan
-Truck to sleep
-see if ACC and Lane Centering are working

Is this correct? Because it is not prewired, it is an XL and I will not be adding 360 cam or parking sensors, I will not need the bumper harness? Or does it still need to be taken out and ML3Z15K867NA or (MA) added in? If I used that harness could I avoid going through firewall and just run a custom wire harness from under the glovebox?

Is my understanding of the process correct for my truck? Where i'm most unsure is the bumper harness for my truck and the wiring into the IPMA

Thank you all for being so helpful, just want to make sure I have all the right parts on the way.


UPDATE- edited BA for CA on terminals

I wouldn’t replace the bumper harness in your situation. I would buy the ccm connector with pigtails on it from eBay.
Sounds like you got the rest down.

And the explorer pigtail is ok?

Pigtails.com or Ebay ?? im not sure they are the same connection but I can get the pigtails.com one faster.

I think the CCM module itself is the same so I would imagine the connector is the same. I’ve never looked at pigtails.com and I personally did not even buy the eBay one. I have just seen it referenced here.

There's quite a few shared sensors. Take for instance the BLIS radars, those units have been used in several vehicles for years and can be purchased for around $30 used. This can typically be seen when looking up the part itself. It will often show that it fits hundreds of vehicles as well as listing part numbers it supersedes. 3rd party harnesses on the other hand have no cross reference capability. 3rd party harnesses also come with the possibility of needing to be cut if certain repairs are needed as a harness typically has 2 or 3 dependencies on other harnesses for routing. If the bumper needs removed and a harness just strings wires across the primary harness connection point, those wires will likely be cut during removal.
