Need Autohelm Pin Assignments

[Magic32]

Hello all

I need to know the wire color asignments for the REMOTE port on an Autohelm 3000 (Z073). The wires I need to connect to the REMOTE port are blue, green, red and ground (shield) but I need to know which pin each wire connects to. Inside the Autohelm the pins are numbered 1-4 OR they can be referenced from the "notch". It also appears the red wire might not even be used.

The Autohelm is model AH3000 and it uses NEMA 0183. Specifically I want to wire in a Radio Navigation Interface (Z075) which plugs into the REMOTE port. The plug is missing from the Z075 and so I need to know which wire from the Z075 goes to which pin on the AH3000 REMOTE port.

Can anyone help me? Can you suggest who might help me?

THANKS
