Custom Interface Inc.

GTA Silicon Sponsor!

Your first choice for wire harness design, production and electromechanical assemblies. We offer extensive engineering support and better service than you can find anywhere else.


For low volume or quick-turn wire harness and box builds, we manufacture in our own factory 45 minutes east of Portland, Oregon. For high volume and price sensitive projects, we can source your job through our manufacturing partners in China. Our CAD ability can save your project manager days of time and thousands of dollars. We can provide DWG or PDF documentation of prototypes within a week with one phone call.

We also stock components under agreements tailored to fit your delivery needs. Our fulfillment services are designed to reduce customer service issues by repackaging and/or shipping direct to your customer.
