Abstract: A method of designing a wiring harness using a wiring harness design tool can include allowing a first user to access and edit a first wiring harness design component in a wiring harness design workspace, allowing a second user to access and edit a second wiring harness design component in the wiring harness design workspace at least during a portion of the time that the first user is allowed to access and edit the first wiring harness design component, and displaying the first and second wiring harness design components to the first and second users during at least a portion of the time that access is allowed to the first and second users.

Abstract: A method can include allowing a user to place a first wiring harness design component within a wiring harness topology in a wiring harness design workspace, allowing the user to place a first plurality of ground devices within the first wiring harness design component placed in the wiring harness topology, allowing the user to request an automatic ground combination, and, in response to the user requesting an automatic ground combination, automatically applying at least one electronically stored ground combination rule to a first set of ground devices comprising a plurality of the first plurality of ground devices and automatically combining at least two of the first set of ground devices into a first combined ground device based at least in part on the applied at least one electronically stored ground combination rule.

Abstract: A method of designing a wiring harness using a wiring harness design tool can include creating a first wire option expression corresponding to a first wire within a wiring harness design, generating a wire option expression truth table based at least in part on the first wire option expression, modifying the first wire option expression truth table, and modifying the first wire option expression based at least in part on the modified wire option expression truth table.
