The plug has an "8" adjacent to one corner. Is that the orange wire connection??

OMG Rich just answer someone's question without the links and wild goose chases.
To the OP........orange is pin number 1. Red is pin 8.

ok..thanks..so I will "assume" that the number 8 is next to the red wire pin on the plug...
