  • Necessary for adding accessories that were not original installed on your vehicle
  • May only need one connector, even for multiple new accessories

Maybe your INFINITI came with all of the features and accessories you wanted, or maybe you selected a base model in order to make your own customizations. Regardless, if your INFINITI isn't equipped with a specific electrical accessory you want, it may be time to get an Accessory Service Connector before making any upgrades.

The Accessory Service Connector is usually recommended when installing additional electrical accessories that did not come pre-equipped on your INFINITI, such as Illuminated Kick Plates or Interior Accent Lighting. The Accessory Service Connector comes with a plastic port on one side with colored wires coming from the port. Typically, only one Accessory Service Connector is needed even if you're equipping your ride with multiple electrical accessories. When in doubt, contact your local authorized INFINITI service center for assistance.

The Accessory Service Connector can only function when connected with OEM INFINITI-authorized accessories. Using the connector with aftermarket accessories could lead to damage to your INFINITI or the accessory.

The Accessory Service Connector you see here, part T99F64RA0A, is engineered to fit your INFINITI QX55 2018-2022. Learn more about OEM part fitment for your INFINITI under the What This Fits tab.
