I have some old Cox servos that I want to use. I have JR equipment. What is the correct signal assignments on the servo wires? I can identify Pin 1 on several. Two servos have a blue connector with a white/grey stripe on one wire. Thanks.

most servos use 3 wire just match red with red ,blacl with black[jr uses brown] third wire is the signal could be white,yellow or some other color if memmory serves me cox servos were sanwa which is close to the old airtronics connector.
