HRAP2:SA PCB Question

SOrry guys i am doing this on my ps3 because my computers HDD is fried. So basically i need to know where the Power and Ground are at on a HRAP 2 : SA PCB so i complete this mod i am doing…I dont have a multimeter nor the money to get one right now i was wondering if anyone could help and or post some pictures. Thanks

You don’t need a multimeter to find the grounds. Unscrew the PCB and just look at the traces and find the wires that all share the same traces or, with the controller plugged in, find the wires that you can universally touch to another, resulting in each different button input.

If its the same as this and by same I mean the order of the wires are the same, then use the blue and red wires.
