LWN (2.8L) Custom Standalone Harness/Solution


DmaxSwap.com has worked to develop the cleanest solution for wiring your LWN 2.8L Duramax drivetrain for simple operation with nothing more than power, ground, ignition and cranking signals. This purchase will include conversion of your donor engine to chassis harness, ECM tuning and test starting the system. Additionally you can select the option to purchase a donor harness.

* We do not offer this harness without ECM tuning as every setup is tested before it gets sent to you and requires our proprietary solutions.

** At this time we can only use 2016-2018 LWN donor harnesses.
