2016 Nissan Altima with Avital 5303 and Dball2

I plan to install Avital 5303 with Dball2 for my 2016 Nissan Altima. I have bought all the necessary parts that I can think of. When I bought the Dball2 on ebay, I also paid the seller $5 to flash it. However, then the seller said D2D didn't work with Avital, and said that it had to be hard wired. I searched the forum. I believe the conclusion is that Avital and DBall2 can definitely be connected through D2D mode, but I also read some people saying it did not work well with D2D connection. My question is whether that is still the case. I wonder if firmware upgrades have fixed the issues. Should I just spend the money to get an XKloader2? I have no idea of what settings the seller used when flashing. What I especially don't want is that I find that I have to buy an XKloader2 to fix issues during the installation. I will post my wiring plan tomorrow.

I chatted with someone on www.directechs.com, and was told that Avital and DBall2 should work fine in D2D mode. I still plan to get XKloader2 just in case, though. Here is my wiring plan. Please let me know if there are mistakes, or if there are improvements that can be made.

• Connect DBALL2 and Avital 5303 using XKD2D65 cable. Another connection I plan to make is between the tach wires(H3/2 of Avital 5303 and pin 5 of the red 12 pin connector of DBALL2.
• All other connections for DBALL2 are clearly explained in the installation instructions. I'll just connect 12V, ground, and other wires indicated by solid lines to specified wires. I just need to find out if my car has RF anti-pinch window by checking the connector for passeger side window/door lock switch.
