Yes I was trying to get a quick answer on weather or not the speaker wires are labeled behind the indash radio? I believe they are but just so i have a heads up! Installing a new sub and possibly a new indash receiver!

its on a 03 ranger FX4 level 2

 

Buy a 10 dollar plug from walmart, it plugs into the radio harness after you remove remove the radio, it really easy to put in a new deck.

 

its labeled on my 97 but get the harness to save the head ache
