# FLEX Wires

Your FLEX kit includes 34 sensors connected to 16 red wires, 16 blue wires, and two black wires. &#x20;

### Wire Color Coding &#x20;

The wires are color-coded, making it easier to identify the channel name in PRO and find the corresponding sensor on the cap. For example, if the contact quality is low on channel LA, this will correspond with the blue A wire.

| **Wire color** | **Reason**  |
| -------------- | ----------- |
| Red            | Right wires |
| Blue           | Left wires  |
| Black          | References  |

Each wire is labeled with the channel letter it is connected to. All wires are crimped with a JST gold-plated crimp, which helps improve the EEG signal quality.

### Wire Lengths

The sensor wires come in two lengths:

* The wires for channels A-G (front of FLEX Cap) are 300mm, and
* The wires for channels J-Q (back of FLEX Cap) are 150mm.&#x20;

The different wire lengths minimize excess while allowing for any sensor configuration. &#x20;

# Agent Instructions: 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:

```
GET https://emotiv.gitbook.io/flex-2.0-user-manual/flex-wires-and-sensors/flex-wires.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
