I have just fitted one of the above to my MY95 WRX as far as I know I have connected all the wires to the right place but I was wondering if the l.e.d's should skip up and down through the red/yellow/green ones or give a constant reading?

With the engine warm and Idling the LED's illumination will be erratic as the ECU will be in 'closed loop' control (Hunting for Stoich) and the same when cruising on part throttle. When on WOT you should be seeing the Green LED/'s illuminated indicating a richer AFR.

Part throttle closed-loop should give you "disco lights" through stoich, including lean and rich.
Part throttle open-loop should give you pretty much the same reading as WOT (rich)...
