after digging around (after reading about SJ2 in the users guide) i found the following picture:

so to power the wavtrigger with the FTDI board connected do i need to place a dab of solder connecting the two 5v pads in the SJ2 area (two little rectangle pads beneath the speaker pads)?
I am not an electronics guy per-se’ so just need clarification. I have the jumpers soldered to connect the FTDI board and have connected the FTDI via usb but the wavtrigger board doesn’t appear to be powering on so i’m assuming this is the issue, since i have no other way to apply power at this time.
Also another question just popped in my mind.
Is soldering the SJ2 jumper the best way to power the wavtrigger when using the FTDI basic 5v unit? Reason i ask is i have soldered 6 right angle pins to the FTDI section of the wavtrigger so i could just plug in and go. But doing some more reading on this site i see where Jamie answered someone who was having issues updating firmware and he had to disconnect FTDI from wavtrigger board and then start the firmware update and then quickly connect FTDI .
Would it be better to not solder these pads and order a 6v power supply to connect to the barrel and also connect the FTDI to computers usb? I assume NOT soldering the jumpers will prevent the FTDI from supplying power to the critical areas of the wavtrigger?

Correct. SJ2 is the only way to power the board via a FTDI.

Not better or worse but that will also work. Just don’t provide external power AND power from the FTDI/SJ2 at the same time.
