:: Use a hobby knife to lift the plastic tab on the plug. Carefully remove the wire while you have the plastic tab lifted.
:: Once the wire is removed, you may need to use your hobby knife to push the plastic tab back down into the body of the plug. You will know it is back in the proper place when you insert the wires back into the plug and they are held snugly into place.
:: Next move on to the plugs that hold the wire in place with a tab on the wire.
:: Put the tip of your hobby knife through the hole in the plug and press the metal tab on the wire. While you are pressing, carefully pull the wire out of the plug.
:: If necessary bend the small tab on the wire back out into place so it can lock the wire into place when you insert it back into the plug.
:: Once you have all the wires removed, it is time to put the wires back into the plug in the proper order
:: You now have the wires removed from the plugs. Make sure the tabs on the wires or plugs are pressed back into place so the wires will be tightly held in the plug.
:: Many of the servo and ESC manufacturers use different color codes for the wires. To further complicate things, not all receivers use the same wiring scheme.
