PCM-XY-0008 is a six-branch automotive Ethernet harness developed by Premier Cable. It uses one Aptiv 35237404 six-port female connector at the main end and branches into six Aptiv 35191760 single-port female connectors. The assembly uses LEONI Dacar 647-4 automotive data cable to consolidate six interface connections into one pre-assembled harness.

In automotive electronic systems, separately routing multiple data interfaces from a common main-end location can increase material-management, harness-identification, and assembly work. With defined P1–P7 port identifiers and pin assignments, PCM-XY-0008 provides a centralized physical interconnection solution for multi-interface controllers, development benches, and OEM harness integration projects.

Importantly, six branch connectors do not mean that one Ethernet port can automatically become six independently communicating network ports. This is a passive cable assembly without active switching or data-forwarding functionality. Before use, verify that the electrical definitions of the six main-end interface groups, target equipment ports, and network topology support the proposed connection arrangement.

For automotive electronics manufacturers, system integrators, and OEM customers, Premier Cable can evaluate connector configurations, cable lengths, wiring assignments, and inspection requirements to support sample development and volume supply.

Product Overview

PCM-XY-0008 is a pre-assembled 1-to-6 harness developed for applications where multiple data interfaces are concentrated at one device but must connect to modules in different locations. When equipment interfaces, pin assignments, and network design meet the requirements, it establishes physical connections between the main connector and six branch connectors according to the specified wiring arrangement.

By integrating six connection paths into one assembly, PCM-XY-0008 helps reduce the work involved in separately procuring, terminating, and managing individual cables. It also brings the bill of materials, wiring drawing, branch identification, and inspection procedures into one coordinated process, simplifying installation planning, assembly, and subsequent maintenance for volume-production projects. As a passive harness, it does not actively duplicate data or perform network switching.

Product Features

Six-Port Main Connector

The main end uses an Aptiv 35237404 six-port connector, consolidating six interface groups within one connector assembly. For equipment with the corresponding multi-port interface, this construction helps organize harness exits and main-end installation space.

Six Separate Branch Connectors

P2 through P7 all use Aptiv 35191760 single-port connectors. Each branch has its own port identifier and corresponding pin mapping, facilitating routing and assembly according to equipment interface locations.

Standardized End Protection and Length Options

The product uses black double-wall heat-shrink tubing, with three standard wire lengths and corresponding tolerances provided. These clear manufacturing requirements help unify standards for cable cutting, termination, and appearance inspection, while reducing specification confusion between different batches.

Key Performance Advantages

◆ Clearly Defined Six-Branch Mapping for Troubleshooting

The six contact groups at P1 map separately to P2–P7, giving each branch a defined wiring relationship. If a connection issue occurs, engineers can inspect individual branches using port identifiers and continuity records to narrow the troubleshooting scope.

◆ Reduced Management Work for Separate Cables

Consolidating six connection paths into one pre-assembled component helps standardize the bill of materials, cable-length specifications, and inspection records. For repeat OEM assembly, this approach can reduce material-identification and assembly-management work associated with sourcing multiple separate cables.

◆ Standard Length Options for Project Planning

The 0.5 m, 1 m, and 2 m standard lengths accommodate different equipment distances and routing paths. Defining the cable length in advance helps control excess cable and installation space while establishing consistent specifications for procurement, inventory management, and volume production.

Product FAQ

What Is the Difference Between a 1-to-6 Harness and a Six-Port Ethernet Switch ?

PCM-XY-0008 is a passive interconnection assembly that routes six interface groups to six branch connectors according to the engineering drawing. It does not provide active switching, data routing, or data duplication.

An Ethernet switch is an active networking device designed to forward data between network ports. The two products are not interchangeable. If multiple devices need to communicate over a network, verify the controller port architecture and network topology before deciding whether a passive breakout harness or an active switch is appropriate.

Can the Six Branches Connect to Six ECUs ?

This cannot be determined from the harness structure alone. Verify whether the six main-end contact groups correspond to six independent communication channels and whether the target ECUs and network topology support this arrangement. If the main interface provides only one communication link, a passive harness cannot automatically expand it into six independent links.

How Does PCM-XY-0008 Differ from a 1-to-4 Automotive Ethernet Harness ?

The main difference is the port configuration. PCM-XY-0008 uses an Aptiv 35237404 six-port main connector and six Aptiv 35191760 branch connectors for six interface groups, while a 1-to-4 harness has four branches. Select the configuration according to the equipment interfaces and network design, not branch count alone.

Can Premier Cable Provide Wholesale Supply and OEM Customization ?

Standard lengths, special cable lengths, wiring assignments, and inspection requirements can be evaluated according to project needs. For quotation, provide the complete connector part numbers, equipment interface drawings, branch functions, target cable lengths, and testing requirements to confirm the configuration, pricing, minimum order quantity, and lead time.
