HRAP VX-SA, PS360+, Select/Guide Button Question

So my friend want’s to make his Hori UMvC3 X360 stick (aka HRAP VX-SA?) dual modded since the Cronus is now being a piece of crap. He doesn’t really care how I do it as long as it works on both the PS3 and 360.

I understand how to hook everything up except the select and guide buttons. My question is how do I go about with these 2 buttons? I saw some videos where a guy soldered the wire from the PS360+ to the PCB on a MadCatz TE stick. Can I do the same with the HRAP?

Sort off, you still find the guide and select buttons and solder wires to them going to your PS3 PCB that you dual-modding with
