I've read on this forum that some trucks are pre-wired for the audiophile sub and some are not. I want to add the audiophile sub to my truck, but can't seem to find the plug. I found an opening in the carpet where I think the plug should come through and have stuck my fingers in and felt around with no luck. If your truck is pre-wired, how hard is it to find the plug? Is it under the carpet?

 

its usually under the carpet. If not, the wire/plug assembly is relatively cheap at the dealer....$30

I ahd a friend wire his this way, and simply ran it aroudn the kick panels up to his deck...took him about 30 mins to do it

 

One other question...

Does this wire/plug assembly plug directly into the amp or is there a "pigtail" from the amp to this plug?

Thanks,

Fordnoobie,
I also have an FX4 Supercrew. May I ask you where this opening is for the sub/amp? I also want to find out if my FX4 has been pre-wired.

Thanks,

axe124,

Open the driver side rear door. Flip the rear seat up. There is a metal bracket at each end of the seat that the seat rests on. These brackets are what the sub/amp mount to. There is an L-shaped cut in the carpet next to the bracket closest to the driver side rear door. I'm assuming this is where the sub/amp wiring would come through. I will be at the dealership this weekend and will look at a supercrew with the audiophile option to confirm.

Fordnoobie,
Thanks for the speedy response. I found the hole, but only could reach with my finger a little bit. I did not find any wires. How far down would they be? Have you decided on what kind of system you are going with yet? Not sure if I should upgrade to the audiophile system, or just upgrade my sreakers, and maybe an amp. Whats your opinion?

axe124,

I was planning on installing the audiophile system because I want it to be all stock. That way I wouldn't have to rip it out when it came time to sell the truck.

 

Would anyone happen to know the part number for the wire/plug assembly that runs from the head unit to the sub/amp? My local dealer can't seem to figure out how to order this harness.

Thanks,

FordNoobie

 

Anybody get that part # yet? That would come in handy big time. T cant find the plug assembly ano my own,

Thanks in advance,

I HAVE THE AUDIOPHILE HU AND DOOR SPEAKERS (W/TWEETERS) AND SUB ON THE WAY TO MY HOUSE. I AM GOING TO INSTALL THIS WEEKEND. I WAS TOLD THAT THE HARNESS I NEED IS
71-5520-1 OR 70-5520. IF YOU SEARCH FOR FORD HARNESS WITH THESE PART NUMBERS ON MSN THE AVAILABLE SITES WILL SHOW UP. I WILL LET ALL KNOW HOW IT WENT. I DO HAVE A PLUG TAPED TO THE DASH BEHIND MY CURRNET HU, BUT I THINK IT IS FOR A DVD CONNECTION. CAN ANYBODY HELP WITH THIS QUESTION. I ALSO FOUND THE HOLE IN THE CARPET BUT NO PLUG THERE THAT I CAN SEE. I HAVE A 04 SCREW.

 

Connector 71-5520-1 will plug into the head unit. You still need a connector to plug into the sub/amp. I have a copy of the wiring diagram which has a connector number (C3020), but the local dealer says this is a reference number only and he can only order the connector if he has the part number. If I knew this part number, I would order the connector and make my own wiring harness.

 

I Believe the part number you are looking for is 3U2Z-14S411-CAAA, I got it from Oemfordparts.com. could I also get a copy of the layout.

 

Hey, if someone comes up with the information on this wiring harness, I would be interested in getting one. I just purchased a F150 Audiophile Subwoofer from EBay and will need one to hook it up. I upgraded the one CD player that came with my truck with a 6 CD player and there seems to be an empty socket on the back of it for the Amp but I can't find a plug under the seat either. Please let me know if anyone comes up with the answer.

I went to Oemfordparts.com and did a search for the part number you supplied but it came back as "No Match". Are you sure that is the right part number? Thanks!!

 

If you send them an e-mail question a quote for the parts they will send it back. I had to do that, the parts are two new in the system.
