1. A system, comprising:
a first control unit of a first harness of a cut loop of an electric vehicle to execute instructions and configured to:
generate a first signal through the first harness of the cut loop of the electric vehicle, wherein the first signal is indicative of a state of the cut loop of the electric vehicle in the first harness, wherein the first control unit is electrically connected to a restraint control module and a battery pack associated with the electric vehicle;
detect, using the restraint control module, an event associated with the vehicle and a change in the first signal above a first threshold level in the first harness coupled with the restraint control module;
wherein the first signal is connected to a ground, and the first control unit is configured to send to a second control unit a message in response to detecting the change in the first signal, and the second control unit provides an indication of the state of the cut loop in response to the message;
receive, from the second control unit of a second harness of the cut loop of the electric vehicle, an indication of a change in a second signal in the second harness above a second threshold; and
cause electrical disconnection of the restraint control module of the electric vehicle and the battery pack of the electric vehicle from the electric vehicle, responsive to the detection of the event, the change in the first signal, and the indication of the change in the second signal from the second control unit.
