1. What wires we are going to use for your own wire harness?

  • Generally, we will provide a price quotation based on your wire style and size specifications in the drawing request. In cases where the wire style is not specified but only the gauge/size is mentioned, we will select a commonly used UL-certified type such as UL1007, UL1015, UL1569, UL1571, UL2464, etc. This approach is adopted due to our extensive stock of these wire types, eliminating the need for customization from our suppliers.

2. What connectors we are going to use?

  • Before quote the price to you, we are generally will ask you if you would consider the Chinese equivalent if they have. If yes, we will try to find out the appropriate replacement, verify its specifications, and send the drawing to you for approval. If you prefer to use original parts, we will quote you the price strictly based on your drawing listed brand and P/N.
  • Don't worry if you choose the original brand part, as we use replacements for mass production.

3. Why do we suggest you consider a Chinese replacement if they have one?

  • The Chinese equivalent generally offers a more competitive price and shorter lead time for purchasing compared to the original brand. Rest assured, we will take full responsibility for their quality control.
