About Us

WIRING HARNESSES:
Portland Wiring Harness builds wire harnesses for automation of all kinds, testing equipment and electrical connections of all kinds, from diesel electric locomotives to robotic farm tractors and factory automation.
Historically, Portland Wiring Harness had a focus on building accurate wiring reproductions produced for classic cars, trucks and aviation; often building discontinued harnesses used to replace worn out factory harnesses. To do this meant gathering rare, vintage and exotic factory equipment from all over the world. These acquired machines and skills were recognized by several autonomous development programs and utilized to build incredibly intricate harnesses with reliability, that are recognized, specifically by the European automotive industry, as being unsurpassed in the world of autonomous robotic operations.
The PWH team has successfully developed new means of creating almost resistance- less and permanent connections that can be relied upon to not fail inside a mathematically calculated window of operational use. T.E.B. Welding, developed by Portland Wiring Harness, has also put into place a set of standards developed from years of experience building high performance harnesses. These standards are, in some cases, far beyond the requirements of the wiring industry. All these lessons and standards have come together to produce the world's most reliable wiring assembly method. This reliability has been recognized and valued by some of the world's largest organizations currently developing autonomous transportation designs.
PWH builds wiring harnesses for transportation, aviation and data of all kinds. We also design and build harnesses for hydraulic control harnesses for use on farm tractors, implements and permanent factory installations. We can create a harness for new electric and autonomous (self-driving) cars, as well as trucks & machines for agriculture.
Portland Wiring Harness builds harnesses for data networks, security systems, battery arrays, automated electrical pumping systems, automated fluid monitoring systems, measurement and control for integrated circuits, manufacturing, robotics, AG automation, heavy equipment, heating and air conditioning (HVAC), testing research, aerospace and control panel building. As the need for autonomous electric trucks and passenger cars increased, Portland Wiring Harness became a key player in designing harnesses for the automation of the autonomous and electric vehicle industry.

TEST EQUIPMENT:
Testing the harnesses or ECU's (Electronic Control Unit) is just as important as building them. Portland Wiring Harness has accumulated the most advanced cable testing equipment. These efforts to be on the cutting edge of testing technology have led us to design, develop and produce testing equipment for many processes beyond harness testing, electric car and truck dielectric withstanding and high potential energy testing far beyond the normal 600 volts.

AGRICULTURAL TRACTOR & IMPLEMENT AUTOMATION:
We build agricultural automation hydraulic control harnesses. Portland Wiring Harness has what it takes to get your implement fully wired and automated.

ADAPTING OLDER EQUIPEMENT TO NEWER ELECTRONIC SYSTEMS:
We can adapt older agricultural machines to more modern systems. If it can be updated by a cable. We can do it!

HARNESS & ECU:
PWH also produces and reproduces heavy equipment tractor wiring and articulator automation. Over the years, we have reproduced factory harnesses for trucking and automation.

OVER BRAIDING:
Portland Wiring Harness owns and operates braiding machines that allow us to protect wires to military and aerospace standards.

ELECTRONICS & WIRING REPAIR:
Portland Wiring Harness is tooled up and equipped for series production of consumer products. We can work with you for UL approval and any other certifications that might be specific to your product.
