I just purchased the aux-in board from jazzy engineering and have successfully got it installed into my head unit. I'm trying to put everything back together and have an extra plug that I can't figure out where it goes. Anyone know where this is supposed to be connected???
I have no idea why I can't get this figured out. My car is a 2006 Subaru Legacy GT Limited with an OEM sub-woofer installed.
Thanks in advance for the help!
