Its possible the resistor on the lightning adapter is bad. I can send you a replacement and see if that resolves your issue.

That would be fantastic! Let me know what you need from me to do so. Obviously if the adapter isn't the issue I'll make sure the replacement gets back to you.

Do you have the dock from @Ajzride? I can send you the dock integration version as a replacement so you dont have to use that male to male adapter.

Yes I do, that would be perfect.

Is there an idiots screen print guide to all the settings on the comma unit. I have Blue pilot 4.0 and Liquid crystal. what are all the toggles etc. that should be set, etc.

Those that are doing the retrofit:

You may need to lightly file the top corner of the dock for the coupler to seat all the way down, that spot has some support marring that can cause it to not seat fully. Don't go too aggressive, it takes maybe 3-5 strokes of the file to get it right. The thin TPU shim goes on the bottom and the thick shim goes between the coupler and the top plate.

Maybe it's better if I don't post from a phone?

I am taking the plunge! Ordered a comma and q4 harness yesterday!!!!

I also went and submitted the form for the dock/coupler combo! (Keeping a close eye out for the payment email, hopefully you’re not out of stock!)

glad you posted, I had messed up the email address when I confirmed your order

Hey all, I've had my 3x installed and running with no issues on my '23 XLT for the past year with no issues, until the past few weeks. I started getting a "Canbus disconnected. Likely faulty cable error" message on the comma sporadically, and the truck would throw camera and parking sensor errors at the same time. I could usually disconnect my comma (I have a 3D printer and printed a quick-disconnect mount similar to the one Ajzride has designed), then reconnect it, and it would usually come back up and work fine. But, recently, that has not been the case.
I have a Ford Q4 harness that I modified (cut and soldered in an extension). I assumed it was a bad solder joint because when I disconnected the comma, all the errors the truck was throwing went away.
I've taken the harness out, desoldered/resoldered all the connections I made with the extension, to no avail. I'm at my wits' end on this one. I'm not sure what to do at this point other than order a new harness and adapter to try it.
I have probed all the pins on the harness I have, and I have good continuity across all conductors, including the pairs with resistors to prevent start-up errors.
I have also tried swapping out all the USB cables from the harness box to the comma and eliminating all adapters to no avail.
I'm at a point now where the truck is throwing errors when the harness is plugged in, regardless of whether or not the comma is connected on the other end. The only thing I can think to try at this point is to order a new Q4 harness and the lightning coupler to try that combo.
Any help on this would be greatly appreciated.

What's the preferred driving model for 5.0? Not seeing it mentioned in the release notes unless I'm blind which is possible too.

There isn't one. 4.0 was the only one we did that for because there were so many issues with the default model. But I've had good luck running Cool People
