I have a bare bones 2009 F 350. I'm installing a new H/U to replace the stock AM/FM 2 speaker unit. The rear doors are equiped for speakers including the wiring. My question is where do I find the rear speaker wires at the dash? I've traced the wires from the rear doors, under the kick plate and the disappear into the wiring harness. I located a couple of spare plugs behind the stock H/U but they do not appear to be the same color wires found at the rear doors. Any suggestions? All help will be greatly appreciated.
The plug that plugs into your radio contains all of the speaker wires. There is no need to look for any other plugs.
