Yes, the wiring diagram for wiring the # 119250KIT wiring harness is in the instructions (see link). You will need to attach the wires from the converter on the harness by function only using the included circuit tester.

Your 2006 BMW X5 has a 3 wire Multiplexed wiring system that requires a different wiring configuration. Your vehicle has a combined stop and tail light circuit and an additional tail light wire. You will attach the red stop light wire to the combined circuit and the brown tail light wire to the independent tail light circuit.

You will then need to connect the yellow wire to the left side turn signal and the green wire the right side turn signal.

Finally you will need to attach the power wire to the vehicle battery through the included inline fuse to protect your vehicles sensitive wiring and circuitry.
