I do have the LUX/B&O system but don't have any idea what the "eCall option" is. I did use it on the center speaker (as well as the two corner dash speakers) and it worked fine.
I did find this out when doing a Google search...
How does the eCall part of FordPass Connect work?
A: eCall...
FYI - I ordered one and really like it. I did the shift pattern in orange to match my Badland's orange accents. I will say that it sits about an inch higher than the factory one so the shifter sits up a little versus the original. Some other people complained about this but I think it's fine.
This is too funny. I received a notification from Crutchfield yesterday that my 72-5603 harness has shipped. You can see I ordered it on 5/27/2023. Maybe you will get yours soon.
To your point, the Metra ones are reversed. The ones from Hoel come with spade clips but they aren't attached. You attach and crimp the the clips yourself. Just make sure you know which wire is positive and which sire is negative coming off the factory harness.
I gave up on Crutchfield and have ordered twice from Hoel. I ordered the last one on 7/3/2023 and received it on 7/8/2023. Worked perfect.

I used this one from Hoel. It worked great. Make sure the +/- is connected correctly.

I cut is so it fits the full length of both the door edge...
I just completed an upgrade to my B&O sound system and wanted to thank @Ksjrb03 and @RagnarKon . The treads https://www.bronco6g.com/forum/threads/b-o-sound-system-complete-upgrade-done-%E2%9C%85.41031/ and...
Just curious about the specifics of your build. I know it was a Badlands. What about hard/soft top, transmission, engine, tow, sas/non-sas, package (lux/high/etc.)?
