OK, the above information thread helped and I got it working! phew...
For all us ozzies out there who don't have WRX but a Liberty B4 Twin Turbo you need to do the following.
[1] Find the cables and connect the two green plugs together, then plug in the white block connector as well.
[2] open up ecuflash and hit read rom.
[3] from the menu choose the year model for your car in my case 2003 which worked under 2001-2003 Subaru Impreza WRX
[4] Once ready you need to have your brant immoboliser off in order for it to set the ingnition to "ON" (this was what was causing my errors) But in other software like ecuexplorer I didn't have this problem, then actual name of the car would come up.
[5] This should then start the read process, once finished you need to save it some how to a xml, which is were I stopped.
[6] Turn off, remove test (green plug) and white loop block.
Hope this helps others. now to repost my ROM for definition request
