# Customizing the Sensor Wires

The number of sensors and wire positions fitted to the connectors is flexible. As a default, all 32 sensors + 2 reference sensors are fitted to the two connectors. 

* On the left-hand side are 16 blue sensor wires and the black CMS wire. 
* On the right-hand side are 16 red sensor wires and the black DRL wire. 

The sensor names (A-Q) match the pin positions (A-Q) on the connector, as shown below.

Each connector has an empty position above the black reference wires. The connectors are standard 18-position, but only 17 positions are loaded with wires. 

Please do not insert the connector into the empty position.

###  How to Remove Unneeded Sensors from the Connector

Sensors that you don’t need for your experimental montage can be removed. 

To remove unneeded sensors: 

1. Use a thin-flat screwdriver or tweezers to lift up the connector’s plastic tab(s).  Lifting the tab will release the crimp locking mechanism. 
2. Pull the wire until you see the gold color of the crimp. 
3. Then, remove the reference wire. 

### How to Insert Sensor Wires to the Connector

To insert a sensor wire to the connector:

1. Place the crimp lock upwards, then
2. Insert the wire and then pull it to ensure it’s locked in place.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://emotiv.gitbook.io/flex-2.0-user-manual/setting-up-flex-cap/customizing-the-sensor-wires.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
