Reading Entries
Name: an abbreviation for what the pin does. This is for identification only.Pin #: order of the pin in the connector.Color: optional color-coding for the wire insulation.- Colors are solely to help visual identification.
 - Colors do not always match the wire colors that usually tail a component; this is meant to maintain internal consistency.
 
See the tips page for details.
This is a more complicated example of an enclosed Ender 5. It has the following differences from the previous example:
- Direct drive (MOTE is in the toolhead bundle)
 - BLTouch (ABL)
 - 3-pin RGB toolhead lights (RGBH)
 - Enclosure thermistor (TC)
 - 2-pin enclosure fans (FC1, FC2)
 - 2-pin enclosure LED lights (LGTC)

Chamber
Although only six (6) pins are used, we here we use an eight (8) position connector to avoid confusion with the Motion #1 (X axis) connector.
