I got my DJI Phantom with Zenmuse H2 and Upgrade Kit from BHphotovideo.com and those guys installed almost everything for me, but not the AVL58 that I also bought from them.
Ok, what I've found so far is thar the Upgrade Kit have a cable ready for the video link. That cable consists of 3 little cables (YELLOW, RED and BROWN).
That those cables can connect the video and the power to the AVL58 replacing the provided cable as this guy says in minute 7: http://youtu.be/oHITo99sZjE?t=7m2s
The AVL58 have a 8 pin input. So what I've done so far is to destroy the AVL58 Tx cable to try to use the 8 pin end to the 3 colorful cables from the DJI upgrade kit.
I found this connection diagram
I bought a soldering gun and I am ready to use it!
Now I have absolutely no clue on how to connect 3 color cables to 8 pins. PLEASE HELP!
