vz ls1 to l98 conversion

Has anyone done a conversion on a vz 5.7 with etc using the 1mb pcm to a L98 without having to us the original 5.7 etc. Apparrently there is a conversion box floating around but i was wanting to check wiring diagrams as to how the electronic throttles are wired on the two vehicles.Anyone had a play with this conversion?All the other stuff ive sorted(sensors , crank tooth count etc.)
Cheers Shane

Some guys in the state have converted their fly-by-wire to cable...Look up GTO conversions
