Justy Air Conditioning Information
Air conditioning season is upon us and since factory installed air conditioning was not offered on Justy models from '87 to present, wiring and technical information are limited to the installation instructions provided in the kits and not in the Service Manuals. To further assist the technician, both quick facts and wiring schematics are provided.HITACHI
1. SOA332A105, which is the first A/C Kit offered for the Justy 87MY, uses a wiring harness for the dash to attach the A/C "ON/OFF" switch and the blower motor.
2. All Hitachi A/C Kits use a pulser system.
3. The Hitachi A/C Kit # 110 uses a separate condenser fan mounted in front of the condenser.
4. The last Hitachi A/C Kits made were # 110 for 89my.
5. Carburetor models FICD is adjusted in a special sequence. See Service Bulletins 02-70-89 and 02-72-89.
WYNN'S
1. Wynn's Kits do not use a pulser system.
2. The Wynn's Kit does not use a condenser fan, it relies solely on the main radiator cooling fan.
3. The Wynn's Kits # 110 will fit 89MY-92MY carbureted and the # 112 MPI.
NOTE:
THE SOA329Y100 KIT WHICH WAS USED TO UPDATE THE WYNN'S A110 KIT TO FIT MPI JUSTY MODELS IS NOT AVAILABLE. YOU MUST USE THE A112 KIT.
4. The Wynn's Kits use a Sanden compressor. Take care not to accidentally mount it upside down. See Service Bulletin 10-62-91.

6. For 1990 base Justy models (carbureted) manufactured after January 5, 1990, VIN 704943 and after, the Wynn's Justy A/C Kit # 110 requires a spacer kit Part Number SOA329Y205. The compressor is moved closer to the firewall to allow clearance for the air suction valve relocation.
