Swapped wires of the fuel injector and coil?

The vehicle was worked on at the garage after few days, the check engine light was on, the vehicle was scanned, misfire code on cylinder one was detected on the engine. After checking vividly, it was observed that the wires of the fuel injector has removed from the connectors and taped. The vehicle wiring has worked on by a technician.
Could I have the wire diagram of the vehicle?

Thank you
