Frequently Asked Questions

What is an LS swap harness with 4L60E?

An LS swap harness with 4L60E is a specialized wiring system designed to integrate an LS or Vortec engine with a 4L60E transmission into your vehicle. It ensures all electrical components communicate properly and function optimally, maintaining the performance of your engine swap.

What is an LS swap harness with 4L80E?

An LS swap harness with 4L80E is a specialized wiring system designed to integrate an LS or Vortec engine with a 4L80E transmission into your vehicle. It ensures all electrical components communicate properly and function optimally, maintaining the performance of your engine swap.

How do I choose between drive-by-wire (DBW) and drive-by-cable (DBC) for my throttle body type?

The choice between DBW and DBC depends on your preference for electronic versus mechanical throttle control. DBW offers more precise electronic control and can be tuned seamlessly with all factory Gen IV components. DBC provides a more straightforward mechanical connection to the gas pedal, however, more wiring and products are required to convert the 58x signals to 24x signals for DBC control and an older 411 (Red/Blue) PCM is required to be used.

What are the benefits of using a standalone LS swap harness for my engine and transmission?

A standalone LS swap harness offers several benefits, including simplified installation, dedicated wiring for the engine and transmission, and improved reliability. It separates the new engine’s wiring from the vehicle’s original system, reducing complexity and potential electrical issues.
