Ok so I finally got around to installing my sub/amp in my 2013 and would like to report 2 changes to the install process.
1. The signal wires to the factory SONY subwoofer in my 2013 are now high-level (amped) inputs directly from the main audio amp. In my 2010, there was a separate amp mounted to the bottom of the subwoofer, therefore the wires going to it were low-level (not-amped) signal wires that could just be spliced in to RCA cables. *To determine which you have, remove your factory sub and look at the bottom. If you see a silver amplifier mounted to the bottom of the subwoofer housing, use the RCA splice method. If you do not see an amplifier, you need a Line Out Converter. I bought a PAC SNI-35 at a local car audio shop since Best Buy was "out of stock" - although they do sell them at Best Buy. I got hosed down for $35 for this part,
don't pay that much. I needed it and couldn't find it anywhere else locally.
There are 4 wires going to the harness from the factory amplifier, 2 sets of +/- signal wires meant for the factory dual voice coil subwoofer.
The wire colors are as follows:
1. purple/green (+), green/white (-)
2. green/purple (+), grey (-)
Cut and splice them to the corresponding positive and negative inputs on your line out converter. Then the line out converter will have RCA outputs which you will connect to your amp. Just follow the instructions for your line output converter, it isn't difficult.
2. The fuse panel in the passenger side front kick panel no longer takes mini-blade fuses like it did on my 2010. I don't know what year Ford made the change, but the panel now takes the low-profile mini fuses. So, my "tap-a-circuit" method outlined in the first post for powering your remote turn-on wire won't work because I just couldn't find a circuit tap with the new type of fuse input.
So, we're going to the accessory trigger wire in the steering column. Easy stuff too. Thanks to Noah at The Car Stereo Company for the advice on where to find the wire.
- Remove the steering wheel shroud. There are 3 5.5mm bolts on the bottom of the shroud that you need to remove.
Once removed, you will be able to separate the top and bottom halves of the shroud on the side closest to the steering wheel. You will see where they're attached to each other on the front by small latch clips. You can use a small flat head to push the latch clip in to release it. Be careful not to pull the back apart because the top and bottom are hooked together with flimsy plastic hooks.
Once you have the front part of the shroud separated, you will be able to lift the top half slightly and maneuver the bottom half around the steering wheel controls and ignition cylinder. Then you will see the hooks holding the back side of the shroud together. Just slide them apart. See hook location below:
Ok, now on the left side you will see a 7-wire harness. You want to unplug it and go after the accessory trigger wire which is the purple/green wire.
Just cut that wire and splice in your remote turn on wire for your aftermarket amp. Solder if you would like but a 18-22 ga seamless butt connector should be good enough.
I used a waterproof butt connector with the shrink wrap ends. I spliced in my remote turn on wire with one end of the accessory wire and reconnected the other end.
*Tip, strip the lone accessory wire side a little long and fold/twist it on its self to make the wire a little thicker. It's a really skinny wire and to use a butt connector big enough to accept both wires on one side, it could be a little sketchy with the tiny 22ga wire alone on the other side.
I taped my connection tight and when wrapped the entire harness for good measure. Then used a zip tie on the closest harness to make sure my new wire wouldn't move and potentially get pulled out.
After that, run your new remote turn-on wire under your drivers side dash and run it down the door sill trim. I already had the passenger door sill panel off from running my main power wire so I just snaked my remote turn on wire behind the console, under the passenger side carpet, in to the kick panel and down the door sill panel since my amp is on my passenger side.
