Product details

    BT DieselWorks offers a custom harness building/modification service to convert your stock Duramax engine harness for standalone operation. This is an essential item to have when retrofitting a Duramax into a non-GM vehicle/offroad buggy/hot rod. Upon receipt of your stock/unmodified/uncut harness, the harness will be disassembled, and all non-essential wiring is completely removed (not just cutoff/hanging connectors) for a clean appearance. Any loose/disintegrated/worn out factory harness electrical tape and/or loom is also replaced and re-wrapped to make the harness look like a brand new factory piece. Standalone harnesses can be setup for use with either manual transmission (or non-electronic automatic transmission) or a factory Allison transmission configuration. Factory cruise control, tap-shift and Air conditioning can be easily maintained, and you can choose between aftermarket instrumentation, or retaining the factory instrumentation. We build every harness to your exact individual specs and to suit your own Duramax-swap project, and we are happy to incorporate any additional custom features or modifications that you might need (extra auxiliary circuits, longer wires, etc) for additional cost.

    An OEM-automotive-grade Delphi fuseblock (rated for underhood use) and relays are integrated into the harness in order to fully delete the factory large GM underhood fuse box. Extra long wires are added for ignition power, battery power, check engine light, starter, tach signal, speedometer signal, OBD-port, and brake pedal signal. Each wire is carefully marked for easy installation into your custom vehicle build. Only the best parts are used to modify/complete the harness, such as: 3M Super33+ Professional Grade electrical tape, OEM-quality automotive-rated TXL primary wire, Delphi connectors/pins/fuse blocks, German-made Tesa tape, USA-made plastic loom, and double-wall sealed heat-shrink-tubing.

***We are one of the most knowledgeable and prominent Duramax standalone wiring harness manufacturers in the industry. Our reputation and professional quality work speaks for itself. We have built harnesses for customers all over the world, as well as several SEMA-show vehicles and network TV shows!***

    Also included in the price of LLY/LBZ/LMM harnesses is a custom ECM base tune. (LB7 pre-flashed ECM is +$125) We will reflash a custom base tune into your ECM to disable the anti-theft/VATS, as well as disable nuisance check-engine lights that would otherwise be automatically set by the ECM for not being installed in a factory GM truck. For additional cost, we can tune the ECM with a custom BT DieselWorks DSP-5 setup that includes switchable (on the fly) stock/economy/tow/street/race tunes via a dash-mounted switch. There is a lot of labor and detail that goes into these custom harnesses, please allow 4 weeks turnaround time.
