Good gravy ! I have wracked my fool head off trying to figure out what wiring harness adaptor to use that plugs into my 2013 base sync unit with 4.2" screen so that I can have a pigtail to splice onto and use for LF-RF-LR-RR speaker input to an amp or DSP. Everything I read wants to use the FOR-11CHK (I think, or similar) and it is for 2015-2019. There is another interface sold on Amazon that says it is for any Ford vehicle. Reviews for both items show write-ups from numerous people who say neither interface will work and/or connect to my factory headunit.

Does anyone here have any insight on where to find and purchase the correct wiring harness adaptor ? Thank you in advance !

Sorry, I'm new here. Guess this is the wrong forum. I will put it again where I think it should be. Thanks.
