This Blue lead is always used in conjunction with a VCI 1 to provide a connection from the Vehicle Server to the Blue ABS diagnostic connector socket found on Discovery series I and some of the latest Classic Range Rovers.
Please note that the diagnostic sockets in these vehicles do not supply power for the Vehicle Server and so this lead should be used in conjunction with LD006 Cigar Lighter Power Lead and Battery Clip Power Lead Adaptor.
This lead also incorporates a pair of standard 4-40 UNC jack screws to allow it to be more securely attached to the VCI 1 which has mating 4-40UNC jack posts.
