sooo...which harness works? or do they both work?

What harness do you cut on this? I think I will be doing this but I am looking for more details.

Below is a picture of how I did it for my 14' and here is the thread where we originally figured it out. Originally some people were talking about building a custom harness and moving pins around, but then somewhere near the middle of the thread someone found this solution on a focus forum. I have not installed this in my 15 yet, but everything I have read indicates it should work. I might be able to put it in this weekend but I'm not sure yet.

I added a kicker EQ to my system, and it made a big difference. Now I can customize my sound the way I like it.

It's a bad picture, but it fits nicely. I hated drilling the two holes to mount it, but it was worth it.




Here's a picture of my AMP mounted behind the rear seat.




This is a picture of the custom duel 10" sub box under the back seat.
I still have room under the small rear seat for a duel 6x9 box.

so does this work for the 15's with MFT?

if so is this correct?:

one side goes from harness to amp for signal in:

the other goes amped speaker signal out of the amp back into the other side of the harness?

does this mean that you don't have to run any additional wires to each of your speakers for the amped speaker signal and it just runs the amped signal through the existing speaker wires in the factory harness?

thanks for your help with this...just trying to understand what's going on.

which bluetooth harness will work for the 15 with MFT?

ChaseD316,
The one I used is ( ISO-SOT-984-w Lead,cable,adaptor for Parrot Asteroid Tablet Ford Fiesta 11) which I purchased on ebay for $16.99.

Once you get it you cut off the connector that were supposed to go to the bluetooth and like you said the wires from the radio connector go to your amp input and the wires on the connector that plugs into your truck harness connect to the amp output which uses you truck wires to feed the speakers.

You will also have to connect the red and black wires from the connectors you cut off together.

You need to make sure that the amp that you are going to use can except a speaker level input or you are going to have to install a line level converter between you radio output and you amp input.

Also in the bunch of wires between the radio and harness connectors there is a green wire which is switched that can be used for your amp remote turn on.

You can install an amp without cutting any of you trucks oem wire!

Related question....what if I just want to add my own amp and sub? Is there a place to tap into the wiring thats NOT behind the head unit? Guessing there's a chance all F150s have some type of wiring run to behind the back seats to make it easy to add the kicker upgrade (as the dealership). Unless they install wiring at the factory for trucks with the kicker package (doubtful).

Also looking into a sound processor. In that case I'm pretty sure I would be accessing the wire harness for the head unit (in my truck its the touchscreen).

Maltpj, Anyway to know if the harness you bought will work with the Sony system. I'm looking to upgrade the door speakers and add an amp (Alpine 445u) to power them.

Crew Man,
My truck doesn't have the sony system, so I don't know if the plugs and the pin outs are the same. Maybe someone that has the sony system can answer that question for you. I don't think they are the same.

Thanks, I've been looking in the aftermarket stereo section as well, awesome write up by another member, but it was a non sony stereo
