Vehicle Wire Harness Replacement 7-Way OEM Connector For 2004 Chevrolet Silverado


Help me put 7 pin on my 2004 chevy silverado 1500 and the colors of wires


Expert Reply:

The factory wiring on your 2004 Chevrolet Silverado may vary and should be tested with a Test Light # PTW2992 before completely installing a Pigtail Wiring Harness # PK11998. With this harness you will be able to use a 7- and 4-Pole Trailer Connector Socket # HM40975 that uses an OEM connector.
