Yesterday evening I got the JOYING unit installed after getting the Metra 70-8112 adapter. While I had the "universal" adapter that I purchased from JOYING, after closer inspection I could not find a connector that had the necessary plugs for the system, thus needing the Metra. That one worked just fine and was pretty much a plug and play. I first connected all the wires bare just to make sure that I had power, antenna, etc. but as has been found you have to splice the two amp+ wires from the stock harness into the system to be able to get the amp to see a power signal and turn on. I didn't really have the time to go through the process of the amp bypass but will likely do that in the future as I do have the ground feedback loop happening (slight hiss that is constant and can be heard at lower levels).
When I removed the factory head unit I found out that apparently someone else had been back there. Found what looked like two different cigarette adapter style plugs plugged into the stock harness ground and power. They had at some point just been stuff behind the unit so not sure what happened or what they had been used for, and why two?!

After removing those and the head unit I got to wiring up the Metra harness after some messing around with the "universal" harness from JOYING. Luckily, their head units come with a pigtail harness and other "ISO" harness, of which I just used the standard pigtail one and soldered it to the Metra.

After that was a little test fitting which the surround needed some clearancing to allow the faceplate to protrude without hitting the back side of the fascia. This was a bit of trial and error, but after about an hour of back and forth I finally got it to fit nicely.

Right now I have the system button illumination set to time delay, so it comes on in the evening on its own. I am not sure where to pull illumination from and still have to go through to wire everything for the backup camera, sub, etc. once I get to that point. May try to work on the backup camera this weekend, depends on what it going on. Would like to bypass the amp so I can get rid of the hiss but not a huge deal breaker right now, nor overly annoying. Thing is that I have a set of Morel Maximo 6 components coming for the front doors today (YEAH!!) so going to get those installed when I get the chance and try to figure out wiring for the reverse camera.
Since the reverse camera has a brake wire that triggers the camera turn on at the stereo, can anyone help with where they may have pulled that that has done a reverse camera install? Also, the illumination?
