Quite a dumb question....

Yes, I have quite a dumb question, that is probably too obvious for even me to be asking.
  Anyway, I was wondering if you HAD to wire your LEDs to the positive point of the PCB as in this diagram:

It can be from any power point on the psp. All the hold switch provides is a switchable ground one.

Thanks. I'm just doing a lot of thinking; it's modding week for me!
