You seem to be the person to ask about AU 5 litre V8, I am currently fitting this motor from 2000 Fairlane to a Porsche 4 speed transaxle to install into a GT40 replica I have pretty much worked out all the connections except ECU pins 15 and 16 which on all wiring diagrams I have found so far say BUS + and BUS - but I have not been able to find anybody to advise me what these are.
I am hoping you can help
Regards
