Installation is relatively easy.

Roll the windows all the way down. Using needle nose pliers, gently remove one end of a wipe (be careful not to damage your paint or glass). They are held in by little metal clips (same as what is on the back of the new ones). Once you get one out, it's easier to pull the rest of the rest of the wipe carefully by hand.

For installation, take the wipe and hold it up to the opening and make sure ALL clips match the holes EXACTLY. If so, then set it in place just above the holes, and press each metal clip into the hole until it clicks in place. Repeat for the other wipes.
