Worked as it should. Would recommend.
I have a 2015 f-150 xl. It came stock with the 4” radio a d my sync. I used this harness to upgrade it to a 8” sync 2 (looking for a sync 3) radio and bezel from a 2015 f-150 lariat. Everything was plug and play, even down to going to dual climate controls from factory. Everything worked. I would recommend buying the new usb media hub and 4” to 8” ob2 programmer module from 4d tech to make the install complete. This was the route I went because I wanted to customize mine a little different than the kit they offered. 4d tech also offers the transformation kit if you’d rather just get it all in one shot and have all the components sent to your door. I managed to do it all for around 600 I want to say. Versus the 1900 the kit costs. It’s all about finding the bezel and components. I bought mine piece by piece over like 3 or 4 months as I found it and then threw it all in once I had everything.

Works just as described. There is a YouTube video to follow. But you will also need to purchase a gps antenna and a sync 3 dual port. Both are available on Amazon. There’s minor glitches for my setup up like I added dual climate controls. I’m purchasing a ForScan module to fix this. But as far as the harness that was purchased, this is exactly what you need for going to the 4” to 8” Navigation. This is plug and play

Don’t buy !!
I would not purchase this product it did not work for my 2015 F-150. Save yourself the time and do some more research before purchasing on Amazon. I installed everything correctly and the screen would not turn on. I went to the Ford dealer and they could not program it to work. Very disappointed with this product.

Plug & play
Perfect for what you need to get the 8” screen conversion in your lower model f series

worked as intented
worked as supposed to, besides the bottom half of the conversion harness disabled me from using the start/stop button, so I simply just didn't use the bottom half of the harness and used the original wires and everything worked fine! if you're buying this make sure you buy a camera harness adapter for the OEM reverse camera to work.

Easy install but issues with phone and heat and air
Not sure what is going on but the heat and air work but bounce between touch screen and bezel knobs. Also, the phone connects great and everything works BUT you cant talk or hear the person on the line. Was pretty easy to install.

Waste of money
Wish I could give no stars it definitely doesn’t work on a 2015 Mustang v6 Don’t waste your time and money.
