Consult your local waste authority for information regarding available
recycling and/or disposal options.
Use and Care
• Stay alert, pay attention to what you are doing, and use common sense
when operating the EZ-Read. Several operational tests require the
engine in the vehicle to be running during testing. Keep all children and
visitors a safe distance from the work area.
• Keep the EZ-Read dry, clean, and free from oil and grease. Use a mild
detergent on a clean cloth to wipe the outside
of the EZ-Read, when necessary.
• Only use accessories that are recommended by AutoXray.

Connect the EZ-Read to Your Vehicle
The EZ-Read EZ-Read communicates with the computer
and sensors in your vehicle through a special
connection cable. The EZ-Read cable is plugged into a
connector on the top of the EZ-Read, and
into a computer interface connection in your vehicle.
1. Locate the vehicle computer connection:
•[OBD-II / GM] On OBD-II and GM vehicles, the connector
is usually located under the drivers side of the dashboard.
On some vehicles, the connector is located behind the kick
panels, ashtray, or radio.
•[Ford / Chrysler 83-95] The connector on Ford and Chrysler
vehicles is usually located in the engine
compartment, along the outside perimeter of the engine com-
partment, or by the shock absorber towers.
NOTE: For additional connection location information, including the
“OBD Connector Locations Database,” please look
at the Customer Support page on the AutoXray
web site (www.autoxray.com ).
2. Make sure that all the pins are straight and that the connecting
surfaces are free of oils, grease, and moisture.
CAUTION: Do not force the cable connector into the scanner or
into the vehicle computer connection.
3. Push the scanner cable and vehicle connectors together firmly.
•[Ford] The EEC-IV Ford connector has a trapezoid shaped
connector and a small square connector next to it. Make sure
