With the hoses installed through the rubber boot and the boot 4” to 6” from the firewall, feed the wiring
harness from inside the passenger compartment, through the firewall and through the rubber boot (See Photos
25 & 26, Page 12, and Photo 27, below).
NOTE: Feed the heater control valve connector through the
boot first. White grease may be used to ease installation.
Press the rubber boot against the evaporator firewall bracket. Install the firewall ring over the hoses. NOTE:
The service port cap on the #10 A/C hose fitting must be temporarily removed to install the firewall
ring. Using (3) 1/4-20 x 1” bolts and (3) 1/4” washers, install the bolts through the firewall ring, rubber boot
and firewall, and into the weld nuts on the evaporator bracket. Tighten all bolts (See Photo 28, below).
Install (2) hose clamps on the heater hoses in the engine compartment at the firewall ring, ensuring that they
are seated past the barb on the fitting (See Photo 28, below).
With the evaporator attached to the firewall, hold the evaporator cowl brace bracket up to the cowl and
evaporator to locate the approximate location of the 7/32” hole to be drilled from the top of the dash under the
defrost vent garnish/cover (See Photo 29, below). Measure 13/16” toward the driver side from the OEM hole
used to secure the defrost vent garnish/cover, and 1/2” down from the rubber windshield seal.
Attach the dash bracket and cowl brace bracket to the evaporator using (2) 1/4-20 x 1/2” bolts. The cowl brace
bracket mounts to the evaporator sharing the driver side dash bracket bolt (See Photo 30, below). Before fully
tightening the brackets to the evaporator, attach the cowl brace bracket to the cowl under the defrost garnish/
cover using the previously drilled hole with a 10-32 x 1/2” pan head screw, 3/16” flat washer and 10-32 nut
with star washer (See Photo 31, below). Tighten the bracket bolts.
Reinstall the defrost vent garnish/cover to the dash.
