Connector Design Library

Save and reuse connector designs across your projects

Last updated: November 30, 2025

What is the Connector Design Library?

The Connector Design Library lets you save frequently used connector configurations with images, cavity names (1,2,3, / A1, A2, B1, B2, etc.), part numbers, and links to purchase connectors. Browse both your personal designs and system library designs in one unified list. Your designs appear first for easy access, while system library designs are clearly marked with badges. Quickly add connectors to your harnesses without re-entering the same information repeatedly.

Understanding Ownership

Identify your designs vs system library designs

Each connector design displays an ownership badge to help you quickly identify who created it and what permissions you have.

Badge Types

Your Design

Designs you created. You have full control - you can view, edit, and delete these designs. You can upload custom images and define custom cavity names.

System Library

Designs provided by Corsa Technic and EZ Wire. The base design is read-only, but you can personalize any system library design by uploading your own custom image and defining your own custom cavity names. Your customizations are saved for you without changing the original system design for others.

Design Sorting: Your designs automatically appear first in the list, making them easy to find and access for your most frequently used connectors.

Customizing System Library Designs

Personalize system designs with your own images and cavity names

Powerful Customization Feature

You can add your own custom image and cavity names to any system library design without affecting the original. Your customizations are saved to your account only, giving you the best of both worlds: access to the comprehensive system library with the flexibility to personalize designs for your workflow.

System library designs come with default images and cavity names, but you may want to customize them to match your specific connectors or naming preferences. EZ Wire lets you add your own custom image and define your own cavity names for any system design.

Adding a Custom Image

1
Click on any system library connector design
Navigate to the detail view of the connector you want to customize
2
Click "Upload Custom Image" button
This option appears if you haven't already uploaded a custom image for this design
3
Select your custom connector photo or diagram
Upload a photo of your actual connector or a custom diagram that better matches your needs
4
Your custom image is now saved
You'll see your custom image whenever you view this design. Other users still see the original image.

Customizing Cavity Names

1
Click on any system library connector design
2
Click "Customize Cavity Names" button
Opens a modal where you can define your own naming scheme
3
Enter your custom cavity names
Use any naming scheme that matches your physical connector: numbers (1,2,3), letters (A,B,C), grid notation (A1, A2, B1, B2), or descriptive names (GND, 12V, CAN_H)
4
Save your custom cavity names
Your cavity names replace the system defaults for this design. You can update or reset them anytime.

Your Customizations Are Private: When you customize a system library design with your own image or cavity names, only you see your customizations. The original system design remains unchanged for all other users. This lets everyone personalize designs to match their specific needs without fragmenting the library.

Searching and Filtering Designs

Quickly find the connector design you need

The connector library includes powerful search and filtering to help you find connectors quickly, whether they're your designs or system library designs.

Search & Filter Options

Search by Part Number

Type any part of a part number in the search box. The list updates as you type to show matching results.

Filter by Manufacturer

Select a specific manufacturer to see only connectors from that brand (e.g., TE Connectivity, Molex, Delphi).

Filter by Number of Positions

Filter to show only connectors with a specific number of positions (e.g., 2-pin, 4-pin, 48-pin).

Filter by Number of Rows

Filter by the number of rows in the connector layout (e.g., 1-row, 2-row, 3-row).

Filter by Sealed Type

Filter connectors by their sealing characteristics (e.g., sealed, unsealed).

Filter by Color

Filter connectors by their housing color when available.

Pro Tip

Use multiple filters together to narrow down results quickly. For example, filter by "TE Connectivity" manufacturer + "12 positions" to find all 12-pin TE connectors.

Best Practices

Tips for effective connector design library usage

Check System Library First
Before creating a new design, search the library - the connector you need might already exist in the system library. You can always customize it with your own image and cavity names.
Customize System Designs When Needed
If a system library design is close but not perfect, customize it with your own image and cavity names rather than creating a duplicate design. This keeps the library organized while giving you the exact configuration you need.
Use Filters Effectively
Combine multiple filters (manufacturer + positions) to quickly find specific connectors, especially as the library grows.
