      <p class="para_topic">A harness design may include wires that terminate with a <em>lug</em> that is attached directly to a device. Examples of such devices are batteries with poles (such as a car battery) and terminal blocks with screws that hold the lugs.
      </p>
      <p class="para_topic">Lugs are of different types, but a common type is an eyelet crimped onto the wire.</p>
      <div class="figure">

      </div>
      <div class="title_figure">Eyelet lug</div>
      <div class="title_division">Lug qualification</div>
      <p class="para_division">Qualify a lug component as a connector. A typical connector has many connections points (pins) whereas a lug only has one or two. Define a multiport in the lug component to which a path may be connected and create one or two virtual ports as needed. You can add a Fitting Port to make adding the component easier by using the <b class="uiTerm">Place Part</b> tool, if desired. The lug shown below has both a multiport for the wire connection and a <b class="uiTerm">Fitting Port</b> for component placement.
      </p>

      </div>
      <div class="title_figure">Qualified eyelet lug</div>
      <div class="title_division">Lug placement</div>
      <p class="para_division">You can place a lug into the harness assembly using either Routing <b class="uiTerm">Place Part</b> or Assemblies <b class="uiTerm">Add Component</b>. If you define a fitting port for placement, Routing <b class="uiTerm">Place Part</b> should be used.
      </p>
      <p class="para_division">Typically, you can place several lugs onto a device such as a terminal block for example. There is no mechanism available for the electrical design system to pass the information into Routing Electrical that specifies which lug attaches to which terminal of the terminal block. In the image below, three lugs are placed onto a terminal block.</p>
      <div class="figure">
         <p align="center"><img align="bottom" src="graphics/lug1.gif"></p>
      </div>
      <div class="title_figure">Three lugs on a terminal block</div>
      <p class="para_division">Each lug has a unique identifier defined in the component list. Through the <b class="uiTerm">Component Navigator Interface</b>, you must assign these designators in order to route the wires. The problem is to determine which identifier to assign to which lug. Since the ports of a device are not uniquely identified, the system cannot automatically make these assignments.
      </p>
      <p class="para_division">There are different ways to resolve this problem. One solution is to have comments provided within the component list that indicate the position of each designator. (This lug goes to terminal block 2 slot 3.) &nbsp;Another solution is to have an attribute or name assigned to each port of the terminal block (SLOT = &quot;J72A&quot;) that can be reconciled with the Unique ID from the component list by the designer. You can devise other such methods according to a defined process.</p>
