RGB Amp Mod Help

I followed this mod and in my eyes all the connection look good.

I bought this cable:

I plugged everything in and got nothing. I read the comments on the cable and someone said they used it with voultars mod but had to swap a wire from V to S. I tried it still no go. I’m in the US. I have a NS1 serial console. So any help or insight would be great.
