Chinese steering wheel controls. Extra button maestro rr

Hello. I have an 07 base model no steering wheel controls, but I am going to install these Chinese ones I bought on AliExpress. Mostly the same except it has an extra rocker switch with what looks like fog light control. When trying to program my maestro, I choose the steering wheel with 2 side controls but there is no fog light section to program. I tried selecting different vehicles in the program, but that didn't work. I can't find a custom button location or anything like that either. Is there anyway I can program.the control In maestro? Would it be because it's a light control so maestro wouldn't have a thing to do with it. sorry all the questions, I've never put one of these in and I'm also installing some Chinese stuff which don't really help. I already have installed a pioneer 8500. Also got my Chinese airbag cover and new clockspring to install. Thanks

 

I assume that being Chinese they have no instructions or crappy ones.

Sorry I have no idea esp with it having an extra button / switch. I hope it doesn't screw up the spiral cable.
