Wire Harness · Application: Inside-the-Unit Wiring

Wire-to-Board Signal Harnesses

Short-pitch harnesses inside the unit: main board to panel, tuner, amp or sensor. Keyed and color-coded so the plug only goes in one way.

Fan-out & 1-to-1: from a main board plug to panel, tuner and amp connectors
Small-pitch connectors: 2P to 16P and up, keyed and polarized
Color-coded conductors: fast assembly and easy service
Clean terminations: consistent crimps with heat-shrink or housing strain relief
Routing-ready: length and breakout points built to your chassis layout

Overview

Inside the Enclosure, Tolerance Is the Product

Internal harnesses fail on fit: a pitch off by a fraction, a length that bunches behind the panel, a branch that misses its breakout. We build these harnesses to your board map with mm-level length tolerance, continuity-check every piece, and label to your service manual.

This line is build-to-drawing, not a retail shelf. MOQ applies.
The board-side pinout must come from your drawing or a sample. We don't guess.
