[sideshow]

you canot interchange fly by wire stuff with non fly by wire

the ecus look the same but internally are different

looms are different

throttle bodies are different

you cannot run mechanical throttle on a fly by wire ecu system
as the ecu will shut down as soon as there is any probs with the fly by wire

im slowly organising afew hard to get parts for when doin these enignes

even the later 6lt engines make it hard to interchange stuff

only stuff u can change is the bare manifold and injectors

but then u have to get wiring modified

its best to just buy a compete set and stick with it

otherwise u will have headaches and need to chase up more parts
