A500/A518 to Gen-III

I thought I saw an assembly just like a carbed setup, only not hooked to a carb. Drilled a hole in the DBW pedal, and ran it like a normal throttle cable hooked to a transmission cable. If that explanation makes sense.
It does, kind of anyway. I would just be curious to hear from someone who has done the switch. There has to be tons of fuel injected Hemi swaps with a 727/904/46RH/? out there.....
