No problem, though it's only useful for that version of DS3 controller. Sony has so many versions of these things now and the TP spots change between some versions as well, the older DS3 and this one are a lot different, so having one set of them done up is really only good for just that controller.
On the MSU_V3.5X 1.12 the TP spots are..
TP1 - 5v (USB connector)
TP2 - D-
TP3 - D+
TP4,5,6 and 7 - GND
TP17 - COM1 (Common line for all buttons on the left of the controller, D-pad and L1/2)
TP18 - COM2 (Common line for all buttons on the right of the controller, [ ], X, O, /\ and R1/2)
TP24 - PS (Home button)
TP25 - Start
TP26 - R3
TP27 - L3
TP28 - Select
TP30 - [ ]
TP31 - X
TP32 - O
TP33 - /\
TP34 - R1
TP35 - R2
TP37 - L1
TP38 - L2
TP39 - DL
TP40 - DD
TP41 - DR
TP42 - DU
TP51 - LED + as well as the other line for the PS button (TP24 + TP51 is PS)
L3, R3, Select and Start all share a Common line, COM3, which has no TP spot. That line has to be hit at a Via or trace, which is odd since the older versions of Six-Axis controllers have a TP spot for it.
