Hi mate-what you've picked up is correct. The neutral-start switch also has wires that indicate which of the 6 positions the lever is in. There is a power-in wire, and there is continuity between that and one of the 6 wires depending on position.
The trans will shift as follows when there is no power to the box.
1/1st, 2/3rd, D/OD. It will not select 2nd. To select 2nd gear you need to gain control over the 2 shift control solenoids (solenoid 1 and 2). The shift control solenoids are used by the ECU to change which gear the car is in. (2 solenoids, 2 positions-on and off, hence 2x2=4 combinations for 4 gears).
To get the box to shift 1,2,3,OD you must use the lever position signal from the NS-switch to control the shift slenoids. (it can be done with relays, transistors etc-pretty easy really.)
I don't believe you will be able to activate the overdrive ratio without making a change to the actual hydraulic circuit in the valvebody.
As for the converter lock-up, all you need to do is supply +ve12V to the solenoid (Solenoid 3) and it locks.
Finally, as for the 4th solenoid, I can't answer as I'm using a 2wd box, but just jump 12v to the wire and see what happens.
If you some more detailed info on wiring, valvebody mods and such I'd be happy to help.

PS-BEWARE OF USING IT WITHOUT SECOND GEAR. THE SLIPPING AS IT GOES FROM 1ST to 3RD CAN OVER HEAT AND FRY THE FRICTION MATERIAL.
