Harness Integration in Wiringly​
Wiringly simplifies the process of creating complete, error-free wiring schematics. Using our interactive digital canvas, you can drop the Haltech Elite 1500 ECU directly into your project, automatically load these pin assignments, and connect them to your power distribution units or engine control units. If you are new to the platform, we recommend starting with our Quick Start Guide.
The platform tracks your wire colors, gauges, and terminal types automatically, compiling a complete bill of materials (BOM) and cutting list for your physical build.
