23-Pin Instrument Cluster Wire Harness Connector – OEM 98957-1138 / 98958-1038 | Male & Female

The OEM 98957-1138 / 98958-1038 are 23-pin connectors used in automotive instrument cluster (dashboard) harnesses. The 23-pin configuration integrates speedometer, tachometer, fuel gauge, temperature gauge, warning light circuits, CAN bus, and illumination circuits for the instrument cluster module. Available in Male and Female variants, bare or with 15cm pre-wired leads.

Key Specifications

Why Instrument Cluster Connectors Fail

Instrument cluster connectors are subject to vibration from the dashboard, heat from the display, and repeated plug/unplug cycles during cluster replacement. Terminal oxidation or housing damage causes instrument cluster blackouts, warning light malfunctions, speedometer/tachometer failures, fuel gauge errors, or U-code CAN bus communication faults with the cluster module. Replacing the connector restores full instrument cluster circuit integrity.

Variant Guide

• Male / Male 15CM – Plug-side connector (OEM 98957-1138)
• Female / Female 15CM – Socket-side connector (OEM 98958-1038)

Installation Steps

1. Disconnect the vehicle battery
2. Remove the instrument cluster from the dashboard
3. Release the locking tab and unplug the original 23-pin connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reinstall the cluster and verify all gauge and warning light functions
6. Clear any U-code fault codes with a compatible scan tool
