You don't need a code reader to axcess engine fault codes on a '92 ford product. With the key off, find the computer test block (firewall, passenger side of engine compartment) and use a clip cord to connect the gray/red wire to the brown wire (brown wire is on a seperate pigtail). Now turn the key to ON (don't crank) and read off the stored error codes from the flashing CEL light on dash.

Stored error codes are flashed in groups of 3. It may take a few tries to get used to reading the faults this way ... LOL.
