Your svg files are not in the correct format and lack layerIds. FritzingCheckPart.py reports the following errors on your part.

The reason pcb isn’t working correctly is that the .fzp file isn’t correct (and parts editor AFAIK won’t usually modify the fzp file, it needs to be copied from a part with the correct number of connectors to work.)

 ![capture](https://forum.fritzing.org/uploads/default/original/3X/c/7/c707cf5de4964d399e85f5b0e4ea78d216c60e84.jpeg)

here we see connector5 works but connector6 doesn’t. The reason is this in the fzp file for the part, connector5 is properly defined with a pcb view defined so the pins work.

```auto
    <connector id="connector5" name="G" type="male">
      <description>GND</description>
      <views>
        <breadboardView>
          <p layer="breadboard" svgId="connector5pin"/>
        </breadboardView>
        <schematicView>
          <p layer="schematic" svgId="connector5pin" terminalId="connector5terminal"/>
        </schematicView>
        <pcbView>
          <p layer="copper0" svgId="connector5pin"/>
          <p layer="copper1" svgId="connector5pin"/>
        </pcbView>
      </views>
    </connector>

```

connector6 is has no pcb connection information and thus doesn’t work.

```auto
      <description>V+ IN TO LED CH4</description>
      <views>
        <breadboardView>
          <p layer="breadboard" svgId="connector6pin"/>
        </breadboardView>
        <schematicView>
          <p layer="schematic" svgId="connector6pin" terminalId="connector6terminal"/>
        </schematicView>
        <pcbView/>
      </views>
    </connector>

```

note pcb view in this entry is an empty group so the pins don’t work. The following tutorials on part making may help (I as you will see, typically don’t use parts editor as it wasn’t completed when development stopped in 2016 and hasn’t yet been finished.) I tend to directly edit the underlying files which I find much easier than fighting parts editor. Both of these tutorials apply to current versions of Fritizng many of the others are for older versions.

I lately learned there aren’t links to the videos in Old\_Grey’s tutorial so you need to do a google search for the title and then they come up on YouTube.
