Locate the control panel wiring harness, and plug the
corresponding connector into the correct cable converter assembly
as shown in Figure 5, below.Once the connector is correctly plugged
into the cable converter assembly, secure the wires to the cable
converter assembly using the supplied tie wraps (See Figure 5a,
below). The tie wrap must be located between the end of the wire
jacket and the step in the cable converter housing, forcing a bend
in each wire as it passes over the step in the cable converter
housing. The head of the tie wrap must fall on the edge of the
housing to remain tight. Ensure that the tie wraps are tight enough
that the wires cannot move (See Figure 5a, below).

Final Steps1.
2.3.4.5.
Using the supplied tie wraps, tie the wires to the control panel
as shown in Figure 10, below. Confirm that wires are secured and do
not interfere with lever operation or cable converter
assembly.Reinstall the control panel into the center console.Plug
the wiring harnesses into the ECU module on the sub case (See
Figure 10, below).Wire according to the wiring diagram on Page
13.Calibration procedure and operation instructions: A. Calibrating
the control panel will set the range of travel for the cable
converters connected to the OEM control panel levers. Performing
this procedure will set the limits of the cable converters at their
highest and lowest points. B. Locate the gray wire with an unused
connector in the wiring harness near the cable harness relay. This
wire is labeled PROGRAM on the wiring diagram on Page 13. C. It
will be necessary to ground the gray wire for approximately five
seconds while moving the controls, so it is sometimes helpful to
attach one end of the white jumper to the vehicle’s ground (for
example, the chassis) and have the other end ready to connect to
the gray PROGRAM wire when the procedure requires it. D. To
calibrate the control panel, follow the calibration procedure on
Pages 11 and 12.
NOTE: Tie the unused wire to the control panel approximately as
shown. Ensure that the wire does not interfere with levers or cable
converter assemblies.

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.
