Linear drive to Robertson AP11 autopilot

[dalraidia]

My AP11 connector has a place marked "bypass clutch" for two wires which come from the hydraulic linear drive. At the connection junction, one connection is marked positive and the other is marked negative. However, the wires coming from the drive are blue and brown, with no indication of polarity. Anyone know which one is which? (The drive itself is from a Nacico YP500 autopilot). Also, there is a red/black pair which comes from the drive and connect to the AP11 at "sol motor", but there is no polarity indicated. Does it matter?

The bypass in most drives is a solenoid coil, and polarity doesn't matter.

The motor connection is important, as the autopilot will reverse the voltage to the motor to move the drive left and right. The usual connection is red to + and black to -. However, in the dockside rudder test, the autopilot will test for the proper movement and automatically correct things, no matter which way you hook the motor up.
