Of the many steps in the process of assembling a wire harness, testing the crimped terminal is a crucial one. If the terminal hasn't been properly attached to the end of the wire, it can cause the wire and eventually the entire wire harness to fail. Most manufacturers use pull testing to assess crimped connections and ensure that terminals are properly attached.

Making sure every crimp is a quality crimp is a critical function of all harness manufacturers. So critical, in fact, that many manufacturers mandate it within their own facilities or those of their suppliers to make sure each crimp meets all customer specifications.
