Locate the driver and passenger side defrost ducts. Attach a 12” length of 2” duct hose to the passenger side
defrost duct, and a 24” length of 2” duct hose to the driver side defrost duct (See Photo 2, below).
Install the (2) defrost ducts onto the OEM defrost duct mounting flanges under the dash, and secure them
using (2) #8 x 1/2” screws on each duct (See Photos 3, 4 & 5, below).
Using a 10-24 x 1 ¼” screw and a 10-24 nut with star washer, install the relay in the passenger compartment
under the dash using the 4th OEM hole from the right as shown in Photo 1, below.
Route the purple power wire to the switched 12V power source on the fuse panel (See Photo 2, below).
Plug the white connector on the heater control valve adapter into the white connector on the main wiring
harness (See Photo 3, below).
NOTE: The passenger side defrost duct has a notch for the OEM wire clip (See Photo 1, below).
