Description Important info about our harnesses…Lead time on harness conversion is generally 3-4 weeks from the time it is received and checked in. At the time of check-in, the harness will be inspected and subject to additional charges (either mandatory or suggested) if there are any issues with wires, corrosion, pins or connectors.We do not support Duramax integration into late model vehicles. This includes any integration with any factory gauges, factory body harnesses, etc. It doesn’t mean it can’t be done, just that we don’t support it. You will not retain control of the AC, tow haul or any other factory features that are controlled through the BCM.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.You will be responsible for wiring your owner starter circuit with neutral safety and your own AC circuit if you are wanting AC. You can still leverage any of the factory AC components you’d like but it will be controlled separate from the harness. We recommend aftermarket HVAC, controls and dryer at least.Gauges: We offer a 10% discount on any available Dakota Digital products with the purchase of our harness (contact us with specific product requests). The harness will retain the OBD port, so you can use that for your gauges or use some of the harness pigtails and add an oil pressure and coolant temp sensor to wire them directly. We recommend the latter if you’re planning to use the OBD continually for anything else because the signal isn’t always strong enough on an OBD splitter to run two devices. The CTS3 monitor can be used as a gauge cluster as well.If you are interested in our standalone harness you can follow our ordering guide, purchase your harness modification a well as the ECM and TCM tunes and we can certainly get it running and driving properly for you.DisclaimerAny 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. Tuning Policy In order to power your project with a Duramax Diesel, it is important to upgrade the drivetrain components to handle the massive power and torque generated. Similarly our wiring harnesses and electrical systems facilitate a clean trouble free install. Potentially the most important piece of the puzzle is a having the proper ECM calibration to not only work with your specific application (trans type, emissions equipment, intake/exhaust) but also with the goals of your vehicle (race, show, tow, marine). This is where our nearly 2 decades of Duramax experience comes in. Non-emission compliant. Intended for off-highway competition use only. This is not intended for dual use. We do not support late model integrations, only swaps into vehicles prior to 1998. We will not provide tuning in your registered, factory vehicle with any types of deletes or non emissions compliant tuning. For your swaps it's up to you to research the guidelines of your location to ensure compliance for your classic, swapped vehicle All of our custom ECM and TCM calibrations are created in house using the latest EFILive software and hardware. We can support any power level depending on the supporting mods of your engine from stock to 1000 HP twin turbo custom built engines. “Tuning For Life” If your purchasing your performance upgrade components from us…All of our customers get free tune updates for the life of their custom vehicle ownership. That means if you buy an upgraded turbo or larger injectors from us…we will update your ECM calibration for free!!! All of our tunes come with 1 free hour of technical support required to ensure you get your engine fired up and help with diagnostic support needed in case your donor engine has mechanical issues. *All custom Calibrations require a completed tune request form including customer contact information so that we can ensure we get it tailored specifically for your application.
