Harness Assembly Instructions

High performance harness manufacture has a significant labour content and trained operators are essential for making high quality assemblies.

Tyco offer harness assembly training courses with modules devoted to each step in the process, including laying wires, shrinking tubing and moulded parts and terminating connectors. Each process has an associated assembly instruction, known as a Code of Practice (CoP).

A finished HarnWare drawing contains all the information required to manufacture the harness and, if required, HarnWare can output a list of the Codes of Practice (CoPs) relevant to the design. Armed with the drawing and the CoP list, a production engineer can rapidly introduce the harness into production.

A selection of CoPs is listed below and a set can be supplied via controlled distribution.
If the required CoP is not available for download please Contact us for hard copies.
