The repair strategy was developed to help reduce repair costs while reducing squeak and rattle conditions.<\/p>\n<p>GM Customer Care and Aftersales (CCA) has released all required components to repair these harnesses. For connectors that have 8 cavities or less, a fully populated pigtail with the correct DuraSeal splice is available. For all connectors that have 9 cavities or greater, a connector kit, DuraSeal splices and terminated leads are available. (Fig. 3)<\/p>\n<p>For smaller harnesses (door, seat, steering column, etc.), the repair strategy is to replace the harness.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-15682\" src=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/12\/F03-w-connector-terminal.png\" alt=\"\" width=\"740\" height=\"480\" srcset=\"https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/12\/F03-w-connector-terminal.png 740w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/12\/F03-w-connector-terminal-300x195.png 300w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/12\/F03-w-connector-terminal-85x55.png 85w, https:\/\/gm-techlink.com\/wp-content\/uploads\/2021\/12\/F03-w-connector-terminal-200x130.png 200w\" sizes=\"auto, (max-width: 740px) 100vw, 740px\" \/><strong>Fig. 3<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Part Numbers in Service Information (SI) <\/strong><\/p>\n<p>The Connector End View section of the Service Information is the source for part number information.
