INFORMATION ON SERVICING PCM'S WITH MYLAR STRIPS
MODELS:
1993 ALL TRUCKS
In a continuing effort to improve the quality of our products, new PCM's are being built with mylar strips inserted in each connector. This mylar strip
reduces the potential for bending connector pins when the PCM is connected to the wiring harness. As the harness is connected to the PCM, this mylar
strip is pushed to the back of the connector. The service units you receive may have the mylar steps pushed back or at the front edge of the connector.
Here are two special guidelines to observe when you notice these mylar strips:
^
Do not attempt to pull out the mylar strips to the front edge of the connector. Due care when servicing these units will prevent bent pins.
^
Do not attempt to remove the mylar strips even if they are damaged. There is enough clearance at the back of the connector for one mylar strip.
