Assuming you mean the plug that goes into the receptacle . . . Its easy. Look at the plug. Attach the green wire to the cround (upside down U shaped). Attach the BLACK wire to the coppery connector. Attach the WHITE wire to the SILVERY connector. Attach plug cover securely. DONE.

My question is WHY did you replace a four prong dryer plug with a three prong! 220 volt Electric dryers require two hot legs, a neutral and a system ground wire. Sounds as though you shunted one of the hots or the neutral. You need to install a four prong plug of the same configuration and wire it exactly as the original.
To correctly wire a three-blade 220-volt plug, you should connect the hot wires (usually black and red) to the brass-colored screws, the neutral wire (usually white) to the silver-colored screw, and the ground wire (usually green or bare copper) to the green screw. Always make sure to follow the specific instructions provided by the plug's manufacturer and to disconnect power before working on any electrical connections.
If you are connecting a 4-prong dryer cord to a 3-prong outlet, the extra ground wire (green or bare copper wire) should be left unconnected. Do not try to ground it by connecting it to the neutral terminal or anywhere else. This is to prevent creating a ground loop and potentially causing a safety hazard.
The significance of the red, black, and green wires in a three-pin plug typically corresponds to their functionality. The red wire is usually the live wire, the black wire is the neutral wire, and the green wire is the earth wire. These colors help to identify and properly connect the wires for safe and correct electrical wiring.
Electrical plug hot wireThe smaller blade of the plug is the hot wire, but both wires are in a way hot. This is because you are working with alternating current. Alternating current changes its direction of flow 120 times a second in the United States. An electrical cord can have different plug types. The most popular are the two and three prong type with the three prong type the smaller straight piece is hot, the larger straight piece is called neutral and the round one is ground. With the two prong you don't have a ground.

To properly wire a 3-prong 220 plug, first, identify the hot wires (usually black and red) and the neutral wire (usually white). Connect the black and red wires to the two brass screws on the plug and the white wire to the silver screw. Make sure to tighten the screws securely and double-check your connections before plugging in the appliance.

A single phase 220 volt power supply typically requires a plug with three prongs, including two hot prongs and one ground prong. The specific type of plug needed may vary depending on the country or region.

220 volt electricity 3 prong plug.
To wire a 220 plug correctly, you need to connect the red and black wires to the hot terminals, the white wire to the neutral terminal, and the green or bare wire to the ground terminal. Make sure to follow the specific instructions provided with the plug and turn off the power before starting the wiring process.
Three phases, one neutral and a GROUND
I wouldn't advise it. Your pressure washer has a four conductor plug for a reason. It requires its two hot conductors providing 220 volts, a neutral which is likely being employed in a small circuit board or safety switch and an earth ground which is needed to provide path to ground for stray current and short circuit protection. Don't reinvent the wheel.
