Westwire Harnessing was founded in 1987 as a build to print harness maker working with the then novel new Raychem heat shrink technology they moved in to their first premises in 1989. In the mid 90's Raychem Ltd used Westwire as one of the first approved harness shops to manage their military harnessing programs. During these years Westwire grew its independence as a one stop shop for harness assemblies. In 1999 Westwire opened an additional site in Cinderford to support a need for more local production on a significant vehicle programme.
