Figure 9. Installing the weatherstripping on the custom plenum.

Locate the V4 RND BLACK 4" grill. Using two cable ties, secure the vanes so that they will not turn. See Figure 8a and 8b. Use a length of the supplied weather stripping under the lip of the grill to prevent air from leaking after installation. Install the grill from the inside of the duct, with the vanes pointing upward. Push the duct and grill back into the hole from which it came. With assistance from outside the truck, reach into the luggage compartment and push the length of 4" duct and one hose clamp over the grill. Push the duct over the grill until the grill is tight up against the duct, then tighten the clamp. Replace the duct, and tighten the screws.

Custom Air Distribution Plenum

Find the metal custom plenum and the passenger side window footwell.

Locate the four (4) V4 RND BLACK grills and line up on the window footwell to mark for hole cutting. See Figure 10. Use a 4" holesaw to cut the holes.

Line the flanges of the plenum with the weather strip- ping. See Figure 9. Place the plenum on the back of the footwell and secure with the 6-32 screws. Trim the

carpet at the bottom of the plenum duct so that the carpet will fold up.

Preparing for mounting the foot- well and air plenum

Before the footwell is mounted back into the truck, the cut out for the duct must be made to allow the duct to extend below the bunk surface. Use the template, as provided in Figure12a or 12b, to cut the hole. Use a 1/8" bit to drill locator holes from under the bunk. Go to the passenger side luggage door, and look up to the rear corner of the bunk. See Figure 11. Find the metal support that holds the bunk, and drill right at the edge at the side of the truck, and towards the rear of the truck.

Re-installing the Footwell

Gently insert the duct into the hole. Direct it down- ward, while pushing the footwell toward the window. Once it is all the way down, put the top flange of the footwell behind the window fascia. Fasten the foot- well to the wall and floor.
