The subject technology is related to autonomous vehicles (AV) and, in particular, to an environmental and electromagnetic seal for autonomous vehicle control systems. The AV includes an autonomous driver system computer (ADSC) fixed to an interior surface of the AV and configured to control the electronic drivetrain, the ADSC including at least one port for connecting with an AV and an elastic conductive cover for selectively sealing the at least port one. The elastic conductive cover comprises a hooking member with an opening that is rotatably connected to the ADSC, cannot be independently removed from the ADSC, and includes an inner surface having at least one extended member with a sealing member that is configured to seal a port of the at least one port.
