I did the same. Lots of places install hitches.
The wire up is apparently the hold up or part of it. When the trailer electrical is hooked up the circuits are checked to see if lights work etc. (Ground? Turn signals? Could determine bulb type by range of draw? If trailer hookup is valid the additional amount of amperage required to move truck to a certain speed could be used by chip to determine weight of trailer and only some guru knows what other chips could be notified so they could adjust function. There could be different chips for with trailer or without along with several additional chips that need to be changed out and maybe need different harness even for those?). With an aftermarket hitch and separate harness even if tow/haul is selected the control chip would be missing important data for optimal operation.). Not to imply that aftermarket hitch and harness would not function adequately. Notice that there is a fuse labeled "after market brake controller". I wonder if anyone has used that for a controller?
The wire harness is probably the actual constraint.
I doubt the Mav hitch wiring harness is make in Ukraine and all the other wiring harnesses in the vehicle are made elsewhere. It's the chips. Ramping up chip capacity requires multi billion dollar plants.
Global supply chains. If companies in Ukraine can't make the harnesses, then other companies need to fill that hole in the supply lines.
Yes and no. In this case, when world economies shut down from pandemic, vehicle manufacturers cancelled a majority of their IC orders fearing huge drop in sales and certain disaster if they tried to keep producing cars at forecasted levels pre-COVID. Semiconductor fab houses then took other orders that filled all manufacturing capacity on their schedule months out. When economies re-opened car manufactures went to order up again and found themselves at the back of the line for factory scheduling.
But it only effects the hitch wiring harness?
From my experience, the hitch wiring is connected to cp360 which cancels some of its functions when you connect to the 4 prong. I tried the led bar below the tailgate and got the warnings. I ended up connecting directly to each taillight and cp360 works as it should.
Need to be more specific on what part of CP360. It you are talking about the parking sensor warnings. Yes, the hitch connector should disable warnings that you may be getting too close to something when it's your own trailer.
So if you search the ford accessory site they now have a ford maverick wiring harness $125 and hitch $336 which ford can install after market. I think the person on Facebook said the ford dealer quoted $750. So more expensive but there is an option now.
