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.

Turn on the ignition switch (Do not start the engine). OFF 2. Move the control levers/knobs to the positions shown. DEF HI FLR DASH HOT COLD OFF HI 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. DEF HOT FLR DASH COLD 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. 9 901406 REV C 10/08/21, PG 9 OF 13 Wiring Diagram www.vintageair.com 232007-VUR TAN ORA BLK WHT JF8 RED WHT/RED WHT/YEL WHT/GRN AC ANNUNCIATOR BACKLIGHT POS BACKLIGHT NEG GND 5V-SW TEMP WIPER MODE WIPER FAN WIPER PRE-WIRED VIEWED FROM WIRE SIDE 232002-VUA A/C (IF USED) GEN IV ECU GEN IV WIRING DIAGRAM REV E, 10/6/2017 TEMP MODE FAN PROGRAM * DASH LAMP (IF USED) *** WIDE OPEN THROTTLE SWITCH (OPTIONAL) ** CIRCUIT BREAKER 30 AMP HEATER CONTROL VALVE * Dash lamp is used only with type 232007-VUR harness. ** Warning: Always mount circuit breaker as close to the battery as possible.

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 8 and 9 for calibration procedure. Blower Speed This lever/knob controls blower speed, from OFF to HI. Mode Control This lever/knob controls the mode positions, from DASH to FLOOR to DEFROST, with a blend in between. Blower Speed Mode Control Temperature Control This lever/knob controls the temperature, from HOT to COLD. OFF DEF HI FLR DASH COLD HOT Temperature Control A/C Operation Blower Speed Adjust to desired speed. Mode Control Adjust to desired mode position (DASH position recommended).

DEF FLR DASH HOT COLD OFF HI Defrost/De-fog Operation Blower Speed Adjust to desired speed. Temperature Control Adjust to desired temperature. Mode Control Adjust to DEFROST position for maximum defrost, or between FLOOR and DEFROST positions for a bi-level blend (Compressor is automatically engaged). 11 DEF HOT FLR DASH COLD 901406 REV C 10/08/21, PG 11 OF 13 Packing List: Control Panel Kit (473271) www.vintageair.com Description Control Panel Assembly, Machined Finish Gen IV Universal Control Harness Nut, 1/4-20, Hex Screw, 1/4-20 x 3/4”, Pan Head Spacer, Control Panel Ground Wire Part No. 473269 232007-VUR 180054 180053 647011 231520 Qty. 1 1 2 2 1 1 No. 1. 2. 3. 4. 5. 6.
