Yiou Guan Optotech Co., Ltd was established in 1992 and specialized in automotive and motorcycle wire harness manufacturing. In the early years, we worked with Taiwanese major wire harness manufacturers for OEM Ford, Nissan, Opel etc. By means of our mature production technology and stable sales growth, we therefore founded another plant in Vietnam mainly producing motorcycle wire harness. Our current customers includes Taiwanese main motorcycle manufactures, KYMCO, YAMAHA, many other domestic auto part manufacturers and some overseas customers. To lower down our cost and to provide customers a most competitive price, we gradually move our automotive wire harnessing technology to Vietnam plant. We look forward to supplying worldwide customers a reliable service with quality goods.
