Common Questions

Custom Harness FAQ

To provide an accurate quote, we need: drawings or schematics (if available), connector part numbers or requirements, wire specifications (gauge, color, length), quantity requirements, and any special requirements. We can also work from concept descriptions or samples if detailed drawings aren't available.

Yes, our engineering team can assist with harness design from concept to production. We offer connector selection, wire sizing calculations, routing optimization, and design for manufacturing (DFM) analysis. We can create drawings and documentation for customer approval.

We have no minimum order quantity. You can order as few as 1 piece for prototyping or small batches for testing. This allows you to validate your design before committing to larger volumes.

Lead times depend on complexity and quantity. Simple prototypes can ship in 48 hours. Standard custom harnesses typically take 2-3 weeks for production. We provide specific lead times with every quote based on your requirements.
