Cheers for the info Datatek, will keep you in mind for the EAS cable when it packs up!
Ok, update on the H/L ratio motor issue..
Disconnected C603 from the Transfer Box ECU and took some resistance measurements,
S1 1 ohm
S2 1 ohm
S3 5.7 ohms
S4 2.1 ohms
moving the shift motor to the opposite limit by applying 12v to pin1 and pin 25 of C603 I then measured:
S1 1.1 ohms
S2 1.1 ohms
S3 1.1 ohms
S4 open circuit
Therefore, I've figured position 2 is at "Zone 2" and position 1 could be either 0 0 1 0 (with a short on the wire going to S3) or 0 0 0 0 (with a high resistance on S3)
*Note.. This is very misleading, as in RAVE a closed switch is referred to as 0 and open as 1 !
Are the measurements at position 1 indicating an issue with S3? (S4 is displaying open circuit in one position so this wire isn't shorted)
As this is my second motor im thinking I may have a short on wire(s) returning to the ECU from the motor position switches - as a fault on both motors in such a short period while not being impossible, is highly unlikely.
I got my hands on a security torx bit and removed the old motor's switch, however discovered that it seems to be a sealed unit, therefore cannot inspect it for problems.
My next intentions are to measure the resistance resposition switches from the plug c658/c558
Anything else I should think about?
Thanks again!

Not at all misleading, standard logic terminology. 0 = switch closed = 0 volts applied. 1 = logic Hi level usually from a resistor = + 5 volts or + 12 volts depending on the circuit.
