You can add new wires that are not part of any cables.
Do the following:
- 
                                                    Select the Wires tab. 
- 
                                                    Right-click and select New wire. 
- Define the wire number. The number can also include text(A1, for example). The number is recommended but not mandatory.
- 
                                                    From the Color drop-down menu, select the wire color. 
- 
                                                    From the Connection type drop-down menu, select the wire type: internal, wire harness, jumper bar, or undefined. 
- 
                                                    From the Type drop-down menu, select the wire type, such as MKEM. The function remembers the last types used. 
- 
                                                    From the Location drop-down menu, select the actual location of the internal wire. 
- 
                                                    Enter an informal name or description for the wire. 
- 
                                                    In the ID field, enter an ID for the wire. 
- 
                                                    If you want to generate multiple wires at the same time, select Generate _ wires and enter the number of wires to create. Every wire gets the same information except for the number, which is generated consecutively (1...5 or A1...A5, for example). 
- 
                                                    If you want to define the From and To information with the Wiring connections function after the wires have been created, select Connect created wires. 
- 
                                                    Save the wire by clicking OK. 
                                                     
                                                
The New wire dialog opens.
