APPLICATION / 02

Automotive & equipment harnesses

Link each harness connection to the relevant terminal or connector-contact documentation.

THE WORKING CONTEXT

Understand the connection task

A harness can combine ring terminals, mating contacts and different wire insulations. Match the terminal family, conductor and tool at each connection rather than assuming one universal plier.

A closer look

Termination and interfaces in a harness

Vehicle and equipment harnesses can combine wire sizes, jackets and interfaces. Some use open-barrel terminals, others machined contacts or ring terminals. Select tooling by the actual contact construction instead of treating the entire harness as one crimp task. LIHENGRIX separates preparation, termination and retention after insertion.

From branch identifiers to connector cavities

For an equipment sensor branch, establish branch identifiers and cavities from the drawing before wire preparation. After termination, insert each contact in its specified orientation, verify retention and complete seals, protection and strain relief. Establish branch length from the assembly requirements rather than stretching the finished harness. Open-barrel terminals require matched forming tools, not a machined-contact indent process.

Task	Relevant tool	Main conditions
Wire preparation	LH-S06	Intact strands, insulation and strip length
Machined contacts	LH-H04	Contact, locator, setting and cavity
Insulated-terminal interfaces	LH-I06	Barrel and mating-interface conditions

Recording changes and rework

Retain the pinout, wire and terminal part numbers and assembly orientation. During extraction, use the appropriate method and record the cavity. Recheck retention and required tests after replacement. Colors assist branch recognition but do not replace wire identifiers.
