The TESTPADS have the same numbers for all ECUs I have seen so far. That means the pads listed that should be used MUST be used. There are more pads but they are for other purposes.
I believe the 07 ECU is exactly the same as the 06 ECU. I'll check whether I still have a Hi-Res picture of the testpads somewhere on my PC. If I do I will post it up.
