LML/LGH Custom Standalone Harness/Solution

$2,150.00 – $3,925.00

DmaxSwap.com has worked to develop the cleanest solution for wiring your LML/ LGH 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 (see video on our ordering guide), tuning your ECM and test starting the system. If you still have your BCM, please send that as well. Additional selections give you the option to purchase a TCM tune, donor harness, donor ECM, donor TCM.

* 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 2011-2014 ECMs and A50/T14 TCMs for Allison applications.

*** Only stock power levels only for LGH/6L90 applications unless transmission is built.

Description

IMPORTANT DISCLAIMER

Your harness is set up for standalone use only which in basic terms means the engine will run and the transmission will function. Due to the complexity of modern vehicles and their control systems, donor vehicle functions, conveniences or “nice to haves” are not offered or supported in any way as follows:

Tow-Haul Mode, Tap Shift, Electric Transfer Case Shifting, Axle Engagement, Duramax Idle Up, Fled Fuel, Starter Solenoid Control, Park-Neutral Starter Interrupt, Shift Interlock, AC Compressor Clutch Control, AC Req Idle-Up, AC Req Fan Control, Cruise Control, Vehicle Lighting, Donor Vehicle Gauge Clusters or any other donor vehicle features/conveniences.

Any attempts to make the above mentioned systems or features function are completely up to the customer and/or the installer.

Modifications will void any warranty or support, so it is crucial that you test start your setup with the harness prior to making any modifications. If you have not made modifications to the standalone harness, have proper tuning and are having issues with your test start, please see our diagnostics form.

This price requires a donor harness. The harness will be inspected and subject to additional charges if there are any issues with wires, corrosion, pins or connectors.
