SRS unit; the airbags could accidentally deploy and cause damage or injuries.
. Before you remove the SRS main harness, disconnect the driver's airbag connector, the front passenger's airbag
connector, both side airbag connectors, both seat belt buckle tensioner connectors, and both seat belt tensioner
