A wiring harness is the same thing as a wiring loom. It is a collection of wires bundled and held together by sleeving or cable ties forming a loom. This loom is routed and fitted with connectors or connections along its length. Many wiring harnesses have multiple junctions and split offs with either bare ends, crimped wires or connectors on the end.
Complex Harnesses are usually made on a loom board. This is a 1:1 scaled drawing onto which we can build the loom. An example of a loom board is shown below. Once a loom board is produced, harness production can be done efficiently. The below shows an example of a loom board (A0 sized) completely produced and used by us for a complex loom from drawings supplied by the customer.
