Clean area thoroughly with soap and water solution and wipe completely dry. Use alcohol pad to prep the tape application area and let dry. Wait until after Tailgate Seal is installed before applying very firm pressure, to secure adhesive bond. If necessary, Tailgate Seal can be removed and repositioned prior to applying very firm pressure. Pictures shown below are for the left sidewall and tailgate gap.
Start 1” below truck bed floor and attach seal to the rear corner edge of the left sidewall extension (FIG 1A). Start from bottom and stop when flush with rubber stop. Cut to fit. Apply light pressure to adhesive. Duplicate for the right sidewall.

 
Continue from the top of rubber stop to the top of sidewall. When nearing top of sidewall, gradually rotate seal 90° counter clockwise so that bulb is facing inward and the taped side of seal is flush with the sidewall at the top (FIG 1B). Apply light pressure to adhesive. Duplicate for the right sidewall.
Start at either end of the tailgate gap and flush with Tailgate Seal on the sidewall. Begin attaching seal making sure to align the top of bulb with the truck bed floor. Peel back liner and attach in sections, apply light pressure to adhesive. If the bulb rolls downwards when closing tailgate and you can see the tape, then seal has compressed too much. This occurs sometimes with spray on bed liners and/or in front of both hinges near the sidewalls. Simply invert seal so that bulb side is down.
Cut a 5" piece and attach to the inside of tailgate, flush with the top, bulb side facing to the left. Apply light pressure. Duplicate for the right side.
Close tailgate. If you see light through the sidewalls, make adjustments by removing the seal and repositioning. If there is still light, then cut pieces of seal as needed and attach to sidewalls and/or tailgate. Do not attach adhesive to seal. After Tailgate Seal is in place, apply very firm pressure to secure the adhesive bond.
