Default Anyone have a EFI wiring diagram for 502 efi ??

I think I may have crossed 2 injector wires putting my motor back together. Does anyone know where I can get a diagram for the injector wires ? I tried BAM's site but it's not readable.

Also, how would a motor act if 2 injector wires were crossed ??
