How do I design a trailer wiring kit for my trailers to provide to Vanguard for quoting?

We can work from your CAD print of your trailer or even a hand drawing. We supply samples and prototypes to make sure your harness kits fit right, every time. Our goal is to help you reduce your labor time as it relates to installation and eliminate any wiring failure once your trailer is in the field or at your dealers’ site.
