The Wiring Harness Manufacturer’s Association (WHMA) has enjoyed a long and valuable relationship with Wire & Cable Technology International (WCTI).

WCTI has courteously granted WHMA a regular column “Connect with WHMA” in each edition to communicate topics, news, etc. to the wire harness and cable assembly industry which it represents. To learn more about the association, visit and to submit column suggestions email

First, a little background on the Wiring Harness Manufacturer’s Association (WHMA) for those of you not familiar with the association. WHMA was established in 1993 and became and an affiliate of IPC in 2019. WHMA is the ONLY organization exclusively serving manufacturers of wiring harnesses, electronic cable assemblies, along with their suppliers and distributors.

WHMA is dedicated to providing our members the technical support, access to leading edge technologies, benchmarking and the ability to network with the leaders of the wire processing equipment, services and manufacturing.

WHMA’s goal is to “LEAD”, “EDUCATE” and “CONNECT” their members to resources that make them industry leaders. WHMA leads by providing members knowledge exchanges of best practices through participation at events, peer networking and sharing valuable information online. Educating the industry with the only industry-consensus standard for the Requirements and Acceptance of Cable and Wire Harness Assemblies, IPC/WHMA-A-A620. WHMA connects their members and promotes the value of building relationships throughout the year. The WHMA membership is currently comprised of over 200 manufacturing companies and over 55 supplier organizations. (There are over 1,100 wire harness and cable assembly shops in North America.)

Despite the name of the association, WHMA is not just about wire harnesses. It’s cables and any type of external electrical / electronic interconnection assembly that connects different pieces of equipment of assemblies. Those in the industry know that these assemblies are often an “after thought”. They are typically the last thing to be considered in the design of the product being manufactured by an OEM.

The membership of WHMA is very diverse in market segments served as well as various applications and requirements. This creates opportunities for multi billion dollars in sales. In fact, according to the latest Bishop Research World Cable Assembly Market report, worldwide sales of cables and harnesses reached $155 billion in 2017 (compared to 2017 worldwide sales of connectors at $61 billion).
