Wiring Harness

Designing custom automotive wiring harnesses is an art form - at least that's how we see it. LMS-EFI started out making bespoke wiring harnesses for the Mazda RX7 platform, but we've expanded over the years to cover several popular platforms, including Honda, Nissan, Toyota, GM LS applications, Ford, and more. Give us your specs and goals and we'll design harness system to fit your needs.
