Yes, I did install it myself. There might be a variance on the unit you get (I'm not sure if the 16" or 10" are much different), mine came with 4 different harnesses, but only 2 were even close. Out of the 2, I picked the one that would match up with more plugs (got lucky the first time). FYI Not all of the new and OEM plugs will be used. With my unit there were Zero instructions or wire diagrams, however, almost all the wires have tags. I have to do a firmware update so I can show you pics of the back if needed. I can also take a pic of the harnesses I did NOT use if that helps. I had to connect a couple of wires between the head unit and harness (E brake and reverse). Everything else is plug and play. The only thing in the car menu I could still not change is the dealer options (headlight delay, auto-lock, etc.) I believe you still have to use Toyota Techstream to change those options up to the 2013 model ( I could be wrong).
After I got it going I wanted to use my rear camera while towing but on mine, the only way to view is to put it in reverse so I added a relay on the reverse trigger wire at the new radio and put in an OEM look-alike switch (see pics). I also added one for the Daytime running lights and relay at the DRL resistor module since the dealer wants $65 to turn it on and off.
BTW Nice Rig!
