Adding Factory Subwoofer to Factory Radio
I borrowed the following article to make a wire harness for the subwoofer after replacing the original head unit with a 6 CD/Satellite Audiophile HU in my '07 Screw. I finished the installation August 25th and everything works and sounds great.
The 2 connectors with leads are a little expensive at $54.00 but well worth it after you hear the results.
The only thing I did different is, I skipped the last step about adding the 2k ohm 1/2 watt resistor.
If you are one of the many like myself who have purchased a factory sub to install in your F150, then here are 2 part numbers you will need.
Some, but not all of the F150's have the subwoofer wiring cable installed as part of the vehicle wiring harness. If your truck does not have it, as mine did not, then you can use these 2 part numbers to order the pigtails that plug into the radio and the sub. Of course your radio head unit has to have the little connection on the back for this to plug into.
The part numbers are:
3U2Z-14S411-DLA: Connector w/ leads that plugs into head unit
3U2Z-14S411-CAAA: Connector w/ leads that plugs into sub/amp
they cost me around 24 bucks each. When ordering, be sure and specify the part number "CAAA" there is another similar part ending in "CAA" and it does NOT fit.
Those part numbers are for use with the factory head unit (if equipped with sub plug on back of unit) and factory subwoofer/amp combo.
If you are going aftermarket you really don’t need either harness, although using 3U2Z-14S411-DLA: Connector w/ leads that plugs into head unit may make it a little cleaner to install as you won't have to tap into the main stereo harness for your audio and remote power signals.
With the 2 harnesses, you would connect the pins/wires between the head unit (HU) and Subwoofer (Sub) harnesses as follows:
You will need about 80 feet of hook up wire for a clean install.
Pin 3 HU -> Pin 9 Sub
Pin 1 HU -> Pin 7 Sub (Should be shielded)
Pin 2 HU -> Pin 8 Sub (Should be shielded)
Pin 4 HU -> Pin 1 Sub (Shield)
These 2 are wired separately:
Hot power +12V -> Pins 5 & 6 Sub
Ground -> Pins 2 & 3 Sub
To avoid the turn on thump of the OE amp you must use ~2k ohm 1/2watt resister inline of the blue turn on lead.

No I have a CD Tape combo unit which is kind of weird but looks ok. I did not know any of them came prewired and I was about to start upgrading the stereo so I hope I have the prewire.
