I will describe it on forum. I last did it on a 2 litre, but have done it on V6s as well. If unwise, Chris and Al will say so.
1. Unclip fuse box above battery, remove battery. On V6 you may choose to move harness from above battery to engine too.
2. Empty power steering fluid reservoir, detach PS reservoir, remove hoses, remove reservoir.
3. Unclip all brake hoses from from bulkhead clips; leave pipes attached to ABS unit.
4. Locate ABS harness and socket; locate the violet coloured locking slide at bottom of plug; insert long screwdriver in the slot at the outside end and pull outwards, wiggle plug a bit and disengage plug from socket.
5. Loosen nut on outside ABS mounting screw; remove nut from inside ABS mounting screw. Bend back heatshield from inner mounting screw, releasing it.
6. Grasp ABS unit and tilt front end upwards to reveal six screws holding ECU to ABS modulator body. Catch bottom mounting buffers if they fall out.
7. Remove the six screws holding ECU to modulator.
8. As you pull ECU off modulator, locate and unplug cable beneath it to motor.
9. Reassembly is reverse of dissembly.
