How to Add USB Ports to 2014-2016 MDX Second Row
 

So the fact that the 2014-2016 Acrua MDX did not have second row USB ports was bugging me. I will fix that.

I purchased a 12V USB adapter and modified the rear center console to accept the port. Now I just need to wire it up.

Step 1: Removing the rear center console trim cover. Get a small ( and I mean small) trim panel removal tool and separate the rear console trim cover. There are nine clips that hold it in place.

Step 2: Towards the bottom there are two connectors that need to be disconnected: one black and one white. Squeeze the center part and remove the plugs.

Step 3: You can now remove the entire rear console trim panel. I moved it to my workbench and then used a T15 torx bit to remove the 7-8 T15 bits that hold the black rear vent piece.

Step 4: This is where you can or could deviate from the directions based on your specific USB ports. I chose a center-based location under the A/V connections. I used a Dremel to take out about a 1.25" diameter hole to put in the USB port.

There is about 2.5" of clearance between the back of the center console and the AC vent piece. Whatever USB port you choose, make sure you don't buy a bigger one.

Step 5: I want to wire the USB port directly to two of the wires from the rear center console plug, but I don't know which one yet. This would be the easiest thing to do.

However, there is also the option to wire the USB port to the center console 12V cigarette lighter adapter. However, that requires another couplease of steps by removing the cup holder rubber mat (and screw underneath), and the center console storage area rubber mat (and corresponding screw underneath), and then wiring the USB port wires to that.

However, I will not do that yet until I can get a wiring diagram of the rear center console so I can get 12V wires to tap into.

I ended up wiring it to the center console 12V cigarette lighter adapter.

If you wire this up to the cigarette lighter adapter in the center console, the black wire is the ground, and the white wire is the +12V wire.

Great work OP

great work! might need to add this in! thank you

Doooo eeeeeet.

Thank you!!! Video Attached
 

I wanted to say thank you to the OP. I could not find a video on this and I have heard a lot of people asking about it. I wanted to credit the OP and post this video. I hope it’s very helpful.

I ended up re wiring the USB port because before, I wired it to the center console 12V adapter, but I ran the wires outside the center console. It was ugly, and it sometimes caught the seat when I moved. I desoldered the wires and then ran the wires near the very top left (driver's side) inside center console. This way no wires get snagged.

@rmoran , that's a great video! Great job!
