Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

Product Features:

• Carquest electrical connectors meet or exceed OE wire gauge, insulation, and terminal material requirements.
• Product constructed to meet all design and operating characteristics as intended by the manufacturer.
