But we are just talking about where the wire connects to the motor aren't we? in which case is fine. but if its the battery harness... don't do what i said.Errm no that's not a good idea. If the battery is just connected to a motor than the motor would spin backwards, but seeing as it's got a whole boards worth of components in there you're more than likely to fry something. Look on the board, usually there is a little polarity sign near to the solder points.
