SERVICE INFORMATION
During April of 1987, approximately 55,000 of the connectors shown in the Illustration were produced with the letters "C" and "D" reversed. This connector is used primarily for the ECM, but is also used in other areas, such as the instrument panel, power seats, and cellular phones. Service parts are also affected.
The connector will work properly, but could cause confusion if electrical troubleshooting is necessary. As shown in the Illustration, row "D" is on the same side of the connector as the "PED" logo.
