It shows you in the pic, its one of the grey ones, follow the one grey plug wire to top of the turret to eliminate the ABS sensor wire for that wheel, it will be the other grey plug

If its still the same and you get a spare ABS ECU (make sure its off same rev car as theyre different), just unplug the existing one and plug it into the new one while holding it in your hand, this saves you fitting it and finding out its not to blame

mine was on a rev4, turned out the ECU was faulty, and the ECU for a rev4 is a lot rarer, took me months to get one from a breakers

thanks for reply folks i've Finally found an abs ecu for the rev4! Ryan you mention in an earlier post to unplug the old abs euc and them plug in the new ecu whilst holding in your hand? can you talk me thru this and also will i need to reset anything after i've fitted teh new ecu inorder to establish if it's worked or not. Should i also unplug the grey service plug in the frunk before fitting the part or just plug and play?

No just plug it in and start the car up. I wouldnt bother screwing it to the bracket and fixing the bracket back under the dash because it might not be the ECU, so pointless changing it if you still have the ABS light on after plugging in the new ECU.
Remove the glovebox and you will see it tucked up under the dash, theres 2 plugs connecting to it, just unplug and pop the plugs into your 'new' ECU, start car up and see if the light goes out. You shouldnt need to reset ECU or disconnect service plug

I recall a brake light coming on (not sure if it was the ABS one), but my pads were worn, fluid was a little low due to the pistons having to push more and enabling the light.
