    This external GPS antenna receives GPS signal for vehicle speed on Holley EFI Pro Dashes. All base dash screens are configured to use this input for speed data.

    Specifications:

    • Built-In Magnet for Mounting Flexibility
    • Double-Sided VHB Tape Included for Permanent Mounting
    • Color: Black
    • Part Number: 554-147

    Install the antenna with a clear view of the sky to the horizon for best reception, label facing down and the black plastic housing facing up. For racing applications, Holley recommends permanently mounting it with the included VHB tape rather than relying on the magnet alone.
