Electrical Wiring Harness

Wire harness is used to bundle wires in electrical systems. Wiring harness is combining wiring wires so that they don’t become loose and wiggle here and there. If wiring harness is not used the wiring wires would hang under the hood and dash board in a vehicle which could be very ugly and dangerous also. Wiring harness safely lay wiring to different part of vehicle like lighting system, engine, accessories and other parts of the vehicle. Wiring harness is made by combining wires together and wrap them in some sort of insulating tape. Inside the harness wires are bundled in groups and joined them with the help of connectors. Multiple pin connectors are used which have plenty of pins like 80 pins per connector.

Wiring harness for car

Wiring harnesses are complex as well as simple in a vehicle system. Usually engine compartment and under the dash board complex harnesses are used. Lighting and some sensors are using simple harnesses. Simple harnesses serve only few circuits and simple applications. Whereas the complex harnesses serves complex harnesses and applications. Sometimes some branch harnesses are separated from the complex harnesses for some specific areas where some parts are installed and they are part of the complex harness. Such case you can observe in the engine compartment where sensor harnesses are joining the main harness.

Wiring harness connection

Mostly insulating tape, cotton or harness plastic flexible tube is used to make wire harness or to protect wiring harness from outside. Some wiring harness have seam in them from where you can open it whenever repair is needed or new wiring addition is required. This seam remains close all the way the harness length and also it remains closed even on bends. Sometimes people do use PVC insulation tape to make wiring harness. Such tape harness works but in the oily environment and in temperature environment it don’t work and it starts unwrapping. Harness tube is a better choice in such a case. They are available in different sizes and diameters.
