Selection & Project Review

01 Application Boundary

An ECU or DCU connector can combine battery and ignition feeds, grounds, regulated sensor supplies, analogue and digital inputs, low-side or high-side outputs, communication buses, shields and reserved circuits. Connector identity is only the first layer.

02 Project Inputs

Provide controller manufacturer and exact part number; vehicle or equipment platform and model year; connector housings, terminals, seals and backshells; mating-face views; released pin schedule; supply voltage and load current; network type; sensors and actuators; branch and splice drawing; installation zone; length datums; protection; quantity; labels; and the required bench, vehicle or environmental validation.

03 Release Records

We translate approved interface data into a controlled drawing, bill of materials, circuit table and test program. Samples are checked for connector fit, keying, wire and seal compatibility, pin mapping, dimensions and the agreed electrical functions before repeat production. Vehicle function, calibration, programming and safety behavior remain system-level responsibilities unless the exact equipment and validation scope are included.

04 Interface Review

Confirm the exact mating interface, pin map, dimensions and installation orientation.

05 Sample Acceptance

Agree the sample configuration and electrical, mechanical or environmental checks required by the project.

06 Change Control

Record changes to materials, drawings and process instructions before repeat manufacture.

Send the part number, drawing or sample to confirm the replacement configuration and sourcing plan.

PROJECT REVIEW / CUSTOM MANUFACTURING

Custom Wire Harness Manufacturing in China

Custom wire harness manufacturing from our China factory, with OEM/ODM project support.

A sample, clear connector photos or a description of the equipment and required quantity is enough to start a review.

Discuss Custom Manufacturing & Sourcing

Start with a part number, drawing, sample or equipment requirement.

Information for an accurate quotation

When available, include drawings and BOM, connector and mating part numbers, pinout, wire length and gauge, branch layout, quantity and required tests. Materials, inspection scope and delivery are confirmed for each project.
