Insert the control harness through the dash opening.
Plug the control harness into the control panel assembly and the ECU on evaporator as shown in Figure 2,
below, and on Page 7. NOTE: Diculty inserting harness connector into control denotes improper
connector orientation. Do not force.
Calibrate the control panel as shown on Page 5 and 6.
Conrm the control panel functionality as shown on Page 9.
Install the control panel into the dash by placing the control panel bracket behind the dash and securing it
to the control panel assembly using a 10-24 nylon locknut (See Figure 1, below).

On Vintage Air Gen IV systems using factory controls, it is necessary to calibrate the system to your specific
control panel. This procedure ensures that the stroke of your control panel levers or knobs is translated into
precise control of the fan speed, temperature blend and mode door position. Please carefully read and understand
these procedures before beginning. The procedure may be repeated as many times as necessary to get it right.
In preparation for calibration, you will need to attach the supplied white ground jumper wire to a suitable chassis
ground. This jumper wire must be easily connected to the gray programming wire located in the main Gen IV wiring
harness next to the compressor relay. During the calibration procedure, you will connect the white jumper to the
gray program wire, which will “teach” the Gen IV ECU the upper limits of the control levers or knobs. The blower
will momentarily change speeds, signaling that the upper limits have been “learned”. You will move the levers or
knobs to opposite extreme positions of their travel and then disconnect the white jumper. The blower will again
change speeds, signaling that the lower limits have been learned and that the calibration procedure is complete.

1. Turn on the ignition switch (Do not start the engine).
2. Move the control levers/knobs to the positions
shown.
3. Connect the white jumper wire to the gray program
wire. Wait for the blower speed to change (Approximately
5 seconds).
4. Move the control levers/knobs to the positions
shown.
5. Disconnect the white jumper wire from the gray
program wire. The blower speed will change,
indicating completion of the calibration procedure.
6. Confirm proper operation of controls. Repeat
procedure if necessary. When finished, tape
over program wire connector with electrical tape to
prevent accidental contact with chassis ground.

On Gen IV systems with three lever/knob controls, the temperature control toggles between heat and A/C
operations. To activate A/C, move the temperature lever/knob all the way to cold and then back it off to the desired
vent temperature. For heat operation, move the temperature lever/knob all the way to hot and then adjust to the
desired vent temperature. The blower will momentarily change speed, each time you toggle between operations, to
indicate the change. NOTE: For proper control panel function, refer to Pages 5 and 6 for calibration
procedure.
