Yes, the MB special pliers are definitely recommended for the job. In addition, Hazet makes a set which I also find useful. They are longer than the MB pliers and are very helpful to remove the wires on models where clearance is tight. The pliers from Hazet are about $47 while the MB ones can be had for around $20. They are made by Lumen.
