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.
