The 1987 Dodge pickup does not have a standard OBD-II code reader port, as it predates the OBD-II system which was introduced in 1996. Instead, it uses an older diagnostic system that typically requires a more manual approach, such as checking for trouble codes through the onboard diagnostic light or using a specific diagnostic tool compatible with the earlier systems. You may need to refer to the vehicle's service manual for specific diagnostic procedures for that model year.
