It’s a little unfair to knock a dealership or a tech for not knowing how to add something like this because it’s out of their scope of work, since add-on harnesses like this don’t exist to them in factory form. The best thing they could do is just “turn down the work” by telling you it can’t be done. If they do bite, the cost WILL BE astronomical. They don’t have the luxury of other people on forums/companies already having put in the time of figuring it out so they can sell the mod all the time.
If I was a tech at a dealership, and I did decide to take on a request like this, (just like when I figure out how to add factory features after the fact), I’d probably charge the customer 3 hours labor to pull up the schematics, figure out the home link circuits and all factory connectors involved, search for the connectors and their terminals and availability, price for the parts, another 2-3 hours labor to build it, and another hour to install it.
That’s not even including the fact that the infotainment home link method is not even added to the truck circuits like it is factory (there is no fused ignition circuit involved with the factory home link, it is supposed to be the UGDO circuit from the BCM, and that circuit would be enabled with alfaobd).
The techs also have another road block (when dealing with all of the factory features that we all know how to add after the fact):
They don’t have tools like alfaobd or JScan to be able to enable any of these features after they install all the parts. Their witech tool is not capable of adding sales like that to enable any of these features.
