you can check the polarity with a VTVM reads either plus and minus when you put the leads to it martin

and red leads are positive black negative univesal color code

Yes all the plugs are wired the same servos battery. You can check this by the pins on the receiver one row is all the and the center row is all the same. Hope this helps.

Yep, compare the plugs on the Cox servos to the connector on the pack you want to use. Some cables will use brown instead of black for negative but they always use a red wire for the positive side.

The label on the receiver or cast in signs on the plastic casing will usually indicate the pin polarity as well.

As I recall Cox / Sanwa had three black wires with a white trace on the signal wire the opposite side is the positive.
