i have this in the sub section but out of the 30 some odd ppl that have read it, noone has replied. someone on here has a great writeup and pics in their gallery on where to find the oem sub harness under the rear seat. who is that person? or can anyone help fill me in on where to find it? thanks...

 

search for 'do i have audiophile?' or anything 'audiophile' that should get you on the right track
but for what its worth, if you lift up your rear seat (drivers side) and look at the carpet, there should be a cut where the wiring harness would come into the cab... if you don't have the audiophile option, chances are you wont find the harness- in 04-05 a handful of trucks on the boards had the harness even though they didn't have the audiophile package... since 05, if you didn't order audio. you don't get the wiring harness.

 

then what did i hook up to the back of my HU??? it fit in the sub plug???

 

i dont know what you hooked up- do you have any pics, or at least an explanation of what you're trying to accomplish?? some more info on your truck would be helpful too- do you have the audiophile headunit?

 

yes i have an audiophile unit i bought...........i have an 06 lariat supercrew and i am trying to install the oem sub............in the back of the head unit, there was a wire taped off to the left that i untaped and it fit perfectly into the sub output of the audiophile HU........i just cant find the other end under the seat......

 

Man, I am in the same situation as you. I called Ford and they said that only 06-07 trucks that had the premium audio system had the sub plug in the rear. All trucks have the plug up front.

I have read the thread the shows were it is at but, I can give you an easy way to tell. Look under your rear driver side seat. Find the 2-3" slit in the carpet. Stick your fingers in there 3-4" back and feel for a plastic screw in the floor panel. If you have the rear harness it will be attached with a clip to the screw. If you feel just the screw, you do not have the harness.

Like I said the dealership said you had to have the 6CD premium HU or the audiophile HU from the factory to have the rear harness. I had the single CD player.

 

Hi - on a related note - anyone have the pinout for the connector under the seat?

Thanks!

 

then where does the plug in teh dash lead..........can you buy the harness and go off the front and just rewire it?

Try these threads. The harness in the back goes dead into the main harness somewhere down the line.

One of those threads has the pin out diagram. Many people have bought the connectors from Ford and made their own harness. I decided it wasn't worth it and bought an aftermarket Probox and sub and ran line out connectors from my original CD player. I listed my audiophile HU on Ebay if anyone wants to look at for purchase.

 

Theres a box around where the sub harness connects to the main harness.



Sub wiring diagram.

 

dang...where did that come from.....that helps alot..........might find out where the wires end up and can tie in there.........

 

Look in my gallerie under misc. pictures. i think there is a pic of that sub wiring harness.

 

Thanks, fellas!

And me being the Search police D'oh!

 

anybody know what kind of wire to use for the signal wire for the sub..or will any type of stranded wire work?...do i really need sheilded wire or can i run the power on the other side of the truck to keep from interfering?..i have the layouts from the dealer and it tells the guage......the 06 is different than the 04 that someone posted on here..........also where should i tap into for power...fuse block, which fuse, battery?....thanks

 

Fuse #38 in kickpanel is subwoofer power fuse. Also would be interested in knowing how the 06 wiring is different than the 04? If you want to keep it noise free shielded is the way to go but I imagine standed will work
