# How to Install and Restrict Wiremod in GMod

> Deploy the powerful Wiremod circuitry system while protecting your server from lag and crash exploits. Learn how to configure Expression 2 (E2) quotas.

## Technical Electronics & Automation

**Wiremod** is arguably the most complex and functionally powerful modification within the Garry's Mod ecosystem. It empowers your community to architect functional computers, automated defensive turrets, and intricate navigation systems using a vast array of electronic components. However, its specialized "Expression 2" (E2) scripting environment can be inadvertently or maliciously misused to trigger significant server-wide lag or kernel-level crashes. This guide ensures you can provide the depth of Wiremod while maintaining absolute server stability.

## Step 1: Installation & Verification

Follow these steps to initialize the Wiremod framework on your server.

<Steps>
  <Step title="Workshop Deployment">
    Add the primary **Wiremod** addon to your server's Steam Workshop Collection.
  </Step>

  <Step title="Initialize the Hook">
    **Restart** your server via the Game Panel to mount the new assets.
  </Step>

  <Step title="Technical Audit">
    Join the server and verify that the "Wire" tab has successfully initialized within your "Q" spawn menu.
  </Step>
</Steps>

## Step 2: Strategic Stability Configuration

To prevent players from executing unoptimized E2 logic that consumes excessive CPU cycles, you must establish strict operational quotas.

<Steps>
  <Step title="Access Expression 2 Settings">
    While in-game, open your **Spawn Menu (Q)**, navigate to the **Utilities** tab, and select **Wire** -> **Expression 2**.
  </Step>

  <Step title="Configure CPU Quotas">
    Adjust the following variables to enforce processing limits:

    * **Soft Quota:** Set to **2000**. (Triggers a warning if exceeded).
    * **Hard Quota:** Set to **8000**. (Instantly disables the chip if exceeded).
  </Step>

  <Step title="Restrict Extensions">
    For security integrity, ensure the `http` and `console` extensions are **Disabled**. This prevents malicious actors from using your server node to launch outbound DDoS attacks or flooding your console logs with irrelevant data.
  </Step>
</Steps>

## Step 3: Administrative Tool Restrictions

If your community requires a higher level of oversight, we recommend restricting the "Expression 2" tool to verified groups (e.g., VIPs or Staff) using the **ULX** framework.

<Steps>
  <Step title="Open ULX Menu">
    Type **`!menu`** in the in-game chat.
  </Step>

  <Step title="Navigate to Sandbox Tools">
    Go to the **Cmds** tab and select **Sandbox** -> **Tool Restrictions**.
  </Step>

  <Step title="Enforce Authority">
    Locate `wire_expression2` in the list and restrict its usage to the `supporter` group or higher. This ensures that only trusted participants can use the most resource-intensive capabilities of the mod.
  </Step>
</Steps>
