Just did this mod yesterday, worked first time, once i figured out the left and right channels couldnt be happier. only issue is i didnt have sheilded audio wire on hand so i may have to redo it at some stage to reduce noise, but otherwise fantastic quality
Also, I tracked down the correct sized spades that go into the F8 Plug, fit perfectly and once they are in there they lock in place. Simple crimp of the wires and its all done.
These should be available from Jaycar/Electus. I bought them from a Leading Edge store for around $3.
