The color of the wires are different for each pedal. Keep note of the color of the wires, and which goes where.

Using a Phillips #1 screwdriver, remove the single 6.2 mm screw holding the ground ring in place.

Using a pair of pliers, remove the three connections carefully.

When pulling on the three connection points, there may be some resistance. Do not pull too hard; if you yank on the cable too hard while it's out, it might damage the cable itself.
