Just as Easy as advertised
This product worked exactly as I hoped as far as adding the RCA connections. Truly plug and play and allowed a novice to do the job with ease. I will note that while it has the amplifier turn on wire it does not have a connection off of the harness, you have to go find another circuit. It does have a cable to make that circuit but it would be simple to just add it to the harness and use the same "wire" the radio uses for this function.

Great
Super easy to install, just remember it will come factor set so you have to turn the adjusters on the RCA connector. You’ll need a very small flat head. Turn both of them all the way to the left. The extra blue remote wire I added a 10 amp fuse with the factor 3 that it comes with and ran it from the amp to the fuse box Uber the hood for my f150 and everything works great. Haven’t blown any fuses. Zero issues.

Doesn’t fit Ford Fusion
This will not work for a 14 fusion. The plugs don’t match up at all though they say it work.

Fuse holder wrong size
2015 fusion hybrid. Fuse holder was to big and would not fit in fuse box. Other than that easy install wire harness matched perfectly

Not exactly as pictured.
I am very familiar with these types of harnesses; I work with them every day, and the GWNOWZZET subwoofer amplifier harness is not as pictured. The photo shows the harness version that has a gauge of thicker wires with solid color-coded wires. The one I received had thinner gauge wires, with each wire having multiple colored wires with silver dots on them. Not that this harness would not work; it will, but I'd like to receive the quality of what is exactly pictured when I order anything off the internet.
