harmon kardon speaker upgrade

[tlnrj]

2023 limited elite harmon kardon ...rear door speakers replaced with infinity ref-9632....note..my speakers had reverse polarity...the wiring harness 72-6514 will not work...get a bad drone at speed...the harness that did work is metra 72-6515...works great, speakers are a real improvement over stock...good luck

I don't know if the same is true for our trucks as it was for my old Mustang, but the Metra wiring harness adaptor for the Mustang required me to repin them as the wiring was also reversed. I think I've heard some here say the same is true that you need to repin the connector for it to be plug n play.
