1
Sketch or concept
Send the idea in whatever form you have: a marked-up print, connector list, photo, existing harness, or a rough napkin sketch.
Wire Harnesses
From rough sketch to approved drawing to finished harness
Hismar Solutions creates complete harness packages for diesel generators, gas generators, control panels, switchgear, and industrial power equipment. Bring us the idea, even if it starts as a napkin sketch. We turn it into an AutoCAD drawing, review it with you, then help build and source the harness.
Custom Harness Workflow
A practical path from field idea to buildable package
Some customers know exactly what connector, branch, wire gauge, and label they need. Others have a machine, a panel, and a problem to solve. We meet the project where it is and turn the requirement into something that can be reviewed, quoted, built, and repeated.
How It Works
Concept, drawing, approval, build
The goal is simple: remove ambiguity before fabrication, then deliver a harness that matches the equipment, documentation, and service environment.

AutoCAD package
We turn the concept into clean wiring diagrams, harness schematics, connector callouts, wire colors, gauges, branches, notes, and bill-of-material inputs.
3
Review and approval
You review the drawing before anything is built, so routing, connectors, lengths, labels, protection, and terminations are agreed up front.

Build and source
After approval, we help source the parts, build the harness, coordinate fabrication, and support testing for the finished assembly.
Examples
Harnesses and wiring packages we can support
Typical work includes generator engine harnesses, control wiring, switchgear interconnects, instrumentation wiring, communication cables, power distribution cables, and fully custom assemblies.
Diesel and gas generator engine harnesses
ECU, alternator, sensor, injector, starter relay, fuel pressure, oil pressure, coolant temperature, intake air temperature, and crank position harnesses.
Control panel and switchgear wiring packages
Point-to-point wiring, terminal block layouts, internal panel harnesses, labeled conductors, interconnect cables, and field-ready documentation.
Custom power, controls, and communication assemblies
Battery cables, shore power leads, CAN, RS-485, Ethernet, generator-to-generator communication, distribution, sensor, and specialty cable assemblies.
