Razer Arcade Stick + Remora!

Hello all,

I know the Remora LED Controller board was primarily designed for Mad Catz sticks, but I am hoping to get it working with the Razer Atrox - hopefully I can get it working and other people will be able to reference this in the future :)
I have no problems soldering if necessary - but if at all possible I'd like to do it without soldering to do this as clean as possible.

The main part of what to do looks very clear (I'm assuming the 8 cables plug into the A/B/X/Y/LB/RB/LT/RT to the buttons and the LEDs)
But I'm not sure on what to do after that. There is one additional cable which I'm not sure if it's the Start/Back cable, the harness, or both? The sheet that came with the board said that in addition to the 8 cables there should be "1 harness with four wires (probably black) and a quick disconnect on each wire." - Picture below (the top cable is the is the harness/start/back cable I just mentioned, the lower cable is one of the 8 arcade button cables)



- So does that one connect to the start/back buttons - or somewhere else? (Although by looking at those cables I don't know if it could connect anywhere else)
- Do I need additional cables to connect the current PCB to the Remora? If so, where can I purchase these cables?
- Is there anything else I'm missing? Are there any other cables that have to be connected to the PCB rather than the Remora?

Here are pictures of the PCB, where everything was plugged into the PCB (not sure if it's necessary but figured best to include it), and the Remora Board and ArcEye 3 LEDs (though I'm sure many/most people here are familiar with it)







Huge thank you in advanced to anyone who helps out and of course I can provide any more information/pictures if necessary!
