There is a decorative cover with " 2.4L Quad" on it, it has 4 bolts, upper left, upper right, lower left, lower right. Remove these 4 bolts and lift up. You may need to rock it back and forth so the boots release from the plugs. Once you have it off it will look like a V. The plugs are down at the bottom.
You don't have wires. Our engine uses spark plug boots.
