Remote Start wiring Help

I have 2013 Honda Accord 2DR with Push-To-Start.

I was able to obtain the Vehicle Wiring from here: Start&make=Honda&model=Accord (Smart Key)#

and I was able to obtain the Viper 4704v Installation guide from The12Volt:

I am panning on using the iDatalink bypass.

As I was looking through the installation guide, the "H3" harness confuses me, like the ignition flex relays wires. Where to do I solder those wires to?
Some wires are self-explanatory, like the accessory/starter output wire connects to the Accessory wire of the car. BUT the car has a second accessory/starter, which wires on the harness I connect it to?
Basically, the Harness (H3) wires 1,2, 5-8, are wires that are confusing me.

Please help me if you can, I really appreciate it! Also don't suggest me to go to a pro installer. I am doing it myself and then post a DIY, giving back to the community for helping me. I am sure a lot of members will love to have a remote start DIY tutorial.

A sketch drawing will definitely help too! Thanks again!

Do you still need to carry both remotes for your keyless access to work? I assume yes?

I am wanting to get a remote starter, but I have a few requirements. I won't be installing this myself, going to my local installer but they were not 100% certain if its possible to get what I want.

Khanh, can you tell me if your setup will do what I want? If so, then I can tell my installer that this setup works.
Car: 2013 Accord Coupe EX-L V6 MT. With pushbutton start and keyless access.

1. Do not want to lose a keyfob to the system. I assume that is what the idatalink is for?
2. Want my pushbutton start and my keyless access to continue to work as normal
3. Want my remote starter to turn on rear defrost (if possible set heat as well)
4. 2-way obviously. 1mile range (standard on top line anyways)
5. If I could get a button to roll up all windows, that would be great as well.

Thank you for your help :)
Can't wait till you finish your DIY
I forgot to add one more thing.

The Honda car starter, when you start the vehicle with remote start, and then unlock your vehicle, it shuts off.
With your system, does it do this? BTW, I have a Manual trans.
