Servo motor wire location

[adamn84]

Some of my parts arrived today for my f350 project, so I'm starting to put the chassis back together.

A while back, while trying to find a way to extend the chassis, I accidently broke off the black and white servo motor wires where they connect to the motor. The motor is mounted on its side, and one wire was on top, one was on the bottom.

Which wire goes to the top connection, (black or white) and which goes to the bottom location?

Thanks in advance.
