I have a spare ECU. Pretty sure it is OK, Also have wiring diagrams and a source that lets you buy the correct coloured wires in small quantities to built your loom. I believe I also know the whereabouts of a spare MAF sensor.
The ECU doesn't have a plug but I just got one from and EF falcon and rewired it.
I'm on the NSW Central Coast. PM me if you are interested. My RS is running full Sierra EFI.
