I would like to buy the two appropriate harness adapters (Male and Female) so I can splice into the factory speaker wires for the rears and door speakers to add an amplifier. I have the premium audio with sync and navigation. Does anyone know the proper adapter part number? My amplifier has direct speaker input so no level converter required here.

I think the Scosche FD23RB and FD23B will do the trick but I am not 100% certain.

Thanks!

 

1) did you get an answer to this 2) can you provide more detail please?

 

Nope I did not. I need to pull the deck out and look evidently.

 

if your trying to add an amp I would find the wire diagram frm the back of the sync splice into those wires and run it to my amp.... but you might get a ground loop noise.

or

find the ford amp remove that and splice in from there that would be the better choice actually thatis tho if they have an amp installed

 

Reviving an old post, I too would like a wiring harness or plug and play solution for adding an amp. I really don't want to splice into my factory installed harness. I would like to simply unplug it from the back to the nav unit then plug in a new harness that would go directly to my amps. That way if there is ever any problems or you want to sell the vehicle all you have to do is just plug back in the stock stuff.

 

it's super easy just get a high to low converter and splice into the back to the rear speaker and just leave it there it's a $15 part and install your amps.

if your in SoCal buy me lunch or beer and parts I'll do it for you.

 

The closest thing that I've found is the Sync Lockpick wire harness (which can be purchased separately pretty inexpensively) which you could easily tap into, and avoid cutting into the factory harness.

I have the Lockpick and this is how my amp is hooked up (tapped into the harness). You could cut everything away from it that you don't need and just use the speaker terminal connections.

FWIW- I had to rip the Lockpick out of my truck due to connection issues with the harness, so I'm back to stock (with exception of the sub connection, which I've replaced). I had to take the Lockpick out of the equation in case it needed to go back to Ford (and since I didn't cut into the factory harness, all is well!). Fortunately, it seems like the Lockpick harness was the issue and I have a new one (free) waiting to go back in. This time around, I think I'll solder/heat shrink all my amp connections.

You can see in the image below where I've tapped into the Lockpick harness for my amp connections. The white plug on the right comes out of the back of the factory nav unit, then speaker wire to my amp, then back up from the amp into the female part of the adapter, where the factory speaker plugs into.
