Overview

Built From the Pin Definition, Not From a Template

Send the pin definition of your head unit — or photos of the connectors and a sketch of the branches — and we map every circuit: power, speakers, illumination, key control, reverse trigger and amplifier remote. The harness arrives labeled and bundled so your installer follows your manual, not guesswork.

Fit & Limits

Where It Fits — and Where It Doesn't

Good fit

  • Factory-plug installs: power, speaker, antenna and CAN leads matched to the car's original connectors. No wire cutting on most models.
  • Screen swaps to an Android unit with the same socket and dash size.

Tell us first

  • Positions near the engine or exhaust: heat there is a different spec. We confirm the harness grade before quoting.
  • Repairing damaged factory wiring — an install kit won't fix a cut loom.
