Steps to remove the BigStuff3 Cam connector from the Main Wire Harness
First, remove the secondary lock (white plastic part on the back of the connector) from the connector
housing. Next, insert the Delphi terminal removal tool into the uppermost section of the housing as
shown in the photo above. While inserting the tool into the pin cavity, gently pull on the wire. The
wire should release without having to aggressively tug on it.
Next, remove all three wires in the same fashion. Make sure that the terminal retention tabs (very
small metal tabs on the back of the terminal pins) are raised back up so that they will lock
correctly into the new connector housing. Failure to raise the terminal retention tabs could
result in a failed connection between the connector and the cam sync drive.
Terminal retention tab must be
pulled back to this position after
removing it from the BS3 Cam
connector housing.
