Quoted from Blackbeard:Ok thanks.
So the back two wires (of original) to the back (non banded) lug of replacement. And the third solo wire to the front lug of replacement without a diode attached to it.
I wonder why the placement of the diode is different on the replacement
It really isn't. The switch doesn't know which blade the diode is soldered to, so as long as you put the wires as Lloyd has instructed, it will be just fine.
