Wire Harnesses

Wire Harnesses

Lear’s wiring expertise is firmly based in our deep knowledge of electrical architecture, from design to routing and packaging to testing and delivery. Wire harnesses are some of the most complex parts in a vehicle and Lear has developed technologies to improve performance and reduce weight.

With Lear’s latest advancements, wire harnesses fit more functionality into less space than vehicle engineers had in the past. As a result, these wire harness architectures are also more intelligent than they were in the past. What makes Lear unique is our technical experience in all of the building blocks of the architecture.

From traditional 12V to 48V, mild hybrid and high voltage wire harnesses, our engineering and manufacturing teams have full knowledge and capability of systems requirements along with adjacent electrical centers, controllers / modules and power electronics to continue advanced development of alternative wire solutions and provide single or bundle shielded wire, with aluminum wire technology available.

Utilizing Lear’s Virtual Proving Grounds, we’re able to predict the physical routing on the engine with a high degree of accuracy utilizing Lear proprietary algorithms. This allows us to develop a solution for our harnesses to insure we are meeting our OEMs specifications and regulations before physical testing even begins.
