G56 Swap

I’m excited to announce that I’m currently working on a prototype Swap Harness to simplify your G56 transmission swap. This harness will be offered in various setups to accommodate the unique configurations of your truck and your specific needs.

The 06 – 12 Complete Swap Harness will provide an all-in-one solution for integrating your G56 transmission into your truck’s electrical system. Here’s how it will work:

  1. Plug C7 Pin Connection:
    • The harness will start at the C7 connector (under the TIPM) and run along the engine bay, with a ground wire connecting to the battery post.
  2. Routing Near C132 Connector:
    • The harness will extend to the C132 plug area, where it will branch into two separate plugs:
      • First Plug:
        • Connects to a secondary harness (included in the kit) with a T-tap/pigtail that integrates into the T41 line on the C132 connector.
      • Second Plug:
        • Connects to a third harness (also included in the kit) that passes through the firewall to the clutch interlock switch.
  3. Transmission Connection:
    • Finally, the harness runs down to the transmission to connect directly to the reverse switch for seamless operation.

Why This Swap Harness?

This harness is designed to simplify the G56 swap process by eliminating the guesswork and ensuring a clean, professional installation:

  • Customizable Options: Available in different setups based on your truck’s year, configuration, and specific swap requirements.
  • Plug-and-Play Design: No complicated splicing or modifications needed.
  • High-Quality Components: Built to withstand the harsh conditions of heavy-duty truck use.

Stay Tuned for Updates!

The prototype is currently in development, and I’ll be sharing updates soon, including pictures, diagrams, and installation instructions. Whether you’re tackling your first swap or looking for a cleaner wiring solution, this harness is designed with you in mind.

Thank you for your patience as I finalize this exciting project!
