Where do i cross the wiresno, when you accidently power the printer with wires connected upside down/wrong you will hear the motor make a 2 second ZZWWIIIZZZZ sound and you will get a general error. no harm done to the printer at all. cross the wires and you should be going into the startup sequenc.
Okay that helps but any insulated copper wire should do fine?I have a roll of CAT5 network cable and just striped a short piece of that to extend the wires to my print feed motor. I did solder them to make sure they got excellent connections and wouldn't vibrate loose.
