Who We Are

Since 1973, Kauffman Engineering has grown from a single site wiring harness operation into a multi-location company with a highly respected role as a worldwide resource and supplier. This growth can be attributed to our core business philosophy and implementation of quality assurance, product development, excellent delivery performance, utilization of teamwork principles, strategic acquisitions, effective marketing execution and unparalleled customer service.

Kauffman Engineering is now one of the largest and most advanced manufacturers of wire harness and cable assemblies in the US headquartered just north of Indianapolis in Lebanon, IN. Kauffman Engineering is comprised of multiple manufacturing facilities throughout the US and Mexico. We manufacture products to our customers' prints and demanding specifications.

We pride ourselves in our ability to be fast, flexible, and reliable by offering the short lead-times, flexible scheduling, and excellent on-time delivery performance. We serve a diverse group of industries including lawn and garden, transportation, material handling, industrial controls, medical equipment, off-highway vehicles, HVAC, agriculture, marine, aerospace and many others.

Kauffman Engineering has always had one goal - to be the best in the business.

Why Kauffman Engineering?


Often discussed but rarely practiced in its truest sense; partnerships are a cornerstone of Kauffman Engineering and our customers. Our mutual success is only achieved with and through customers and suppliers working toward common goals, listening to each other and embracing partnerships.


Results speak much louder than words. We will match our customer retention rate with anyone in the industry and we never tire from hearing "We know you will get it done for us".  Kauffman Engineering understands that without trust and reliability, there is no relationship.


Starting with design revisions and working through quotation, prototyping and new part introductions, Kauffman Engineering resources combine thoroughness with an entrepreneur drive to turn what others may have taken weeks to provide and do it in days or even hours as needed by special request.


Let our knowledge and experience work for you. We bring collective resources and practices from communication, dispensing systems, recreational vehicles, bus, specialty vehicles, truck bodies/trailers, agriculture, climate control and HVAC industries and can apply the best solution to your specific need.


Take advantage of Kauffman Engineering's deep knowledge and experience and use us as a resource.   Wire harness manufacturing and development is our core business and is what we do well. Our vertical integration gives you options to custom design a solution that will not be available to you from most other wire harness companies.


With plants certified to ITAR, CSA, UL, and ISO standards, we understand and embrace the value of quality products and good quality systems. Continued investments in equipment and technology focus on solutions to constantly improve process flow, product integrity and supply chain/inventory management.
