It's all installed and working beautifully - upgraded to firmware 1.02.03.
I went out and bought:
1. Multimeter - thanks to jokiin for this recommendation.
2. Two Add-A-Circuit accessories for tapping into two fuses.
3. A couple fuses of different amperage (I used two 10 amp fuses for the cam). I connected to the AWD Park Assist (red, acc) and the Alarm Siren Control Module (yellow, B+).
4. One Fuse Remover, which makes it very easy to remove fuses from the fuse box. It actually came with a little assortment of fuses.
I couldn't have done this without almost super-hero-like help and support from Jon from Pier28, and also jokiin. Sure, I could have easily gone and paid a professional (which I do recommend), but I enjoy doing things myself very much. It took me a while because I had to do research on how to do everything. In the end, I hardly think a professional would have done much of a better job, if at all.
Recommendation for Do-It-Yourselfers:
1. Be patient, and allocate ample time based on your level of experience. If you're like me and don't know what you're doing but researching and learning as you go along, take it slow.
2. Make your you purchase/borrow the items mentioned above.
3. Make your that you have basic tools like screw drivers and pliers. These will help in removing your interior lining, crimping wires, and removing the bolt when you attach your ground wire.
4. Vehicle's User Manual. This comes in handy when you want to figure out where something is, how to remove something, or what a specific fuse is attached to. If you don't have it then search the Internet for diagrams for your vehicle make and model.
5. To test if a fuse is good, turn the nob on the multimeter to the Ohm icon, then put the red lead from the multimeter on one end of the fuse, and the black lead on the other end of the fuse. It doesn't matter if the fuse is in the fuse box or not.
6. To test a fuse for power/voltage, turn the nob on the multimeter to the DC icon, connect the black lead to a ground near the fuse box, connect the red lead to either end of the fuse. Obviously the fuse must be in the fuse box. The red wire should tap a fuse that goes off immediately when the car goes off (not one that stays on for a while then goes off, like interior lights as Jon pointed out). The yellow wire should tap a fuse that is always on. Be careful when you connect a Add-A-Circuit module in order to tap a fuse --- a lot of these modules say something like "2 to 10 Amps", in which case you should not tap a fuse that is greater.
7. Be gentle when you remove interior lining and trims, the plastic clips that hold them in can break if you do it wrong.
Parking mode and everything works! I tested it and took a test drive. I got the polarizing lens, I recommend it --- check it out
