62-Pin Engine Computer (ECU) Board Connector – OEM 1418883-1 | Black & Grey, Male & Female + 124P

The OEM 1418883-1 is a high-density 62-pin connector used in engine computer (ECU/ECM) board harnesses. This is one of the most critical connectors in the vehicle – the ECU board connector carries every engine management circuit: injector control, ignition timing, sensor inputs (MAF, MAP, TPS, O2, CKP, CMP), actuator outputs (VVT, EGR, throttle), CAN bus, and power/ground circuits. Available in Black and Grey housing colors, Male and Female variants, with 15cm or 30cm pre-wired leads, plus a 124-pin Male variant for dual-connector ECU applications. Available bare.

Key Specifications

ECU Connector Failure – The Most Consequential Harness Fault

A degraded ECU board connector is the most consequential harness fault in the vehicle. Because the ECU connector carries every engine management circuit, corrosion on even a single terminal can cause a cascade of fault codes across multiple systems. A corroded MAF sensor pin causes P0100–P0103 (MAF circuit) and fuel trim faults; a corroded CKP pin causes P0335/P0336 and no-start; a corroded injector control pin causes P0201–P0208 and misfires. When a vehicle presents with multiple simultaneous engine management fault codes across different systems, the ECU connector should be inspected before replacing any sensors or the ECU itself.

Black vs. Grey Housing – Circuit Identification

On ECUs with dual 62-pin connectors, Black and Grey housings identify the two connector positions. The Black connector typically carries power, ground, and high-current actuator circuits; the Grey connector carries sensor inputs and CAN bus circuits. Always match the replacement housing color to the original OEM connector position.

Variant Guide

• Black Male / Black Male 15CM / Black Male 30CM – Black plug-side connector
• Black Female / Black Female 30CM – Black socket-side connector
• Grey Male / Grey Male 15CM / Grey Male 30CM – Grey plug-side connector
• Grey Female / Grey Female 30CM – Grey socket-side connector
• 124P Male – Dual 62-pin combined male connector for ECUs with integrated dual-connector design

Installation Steps

1. Disconnect the vehicle battery and allow ECU to power down completely (5 minutes)
2. Photograph the original ECU connector before disassembly – document all pin positions
3. Use a terminal extraction tool to remove terminals one-by-one from the original housing
4. Transfer terminals to the new housing maintaining exact pin positions – any mis-pinning will cause incorrect ECU operation
5. Reconnect and use a compatible scan tool to clear all fault codes
6. Perform an ECU adaptation reset if required (throttle relearn, idle relearn)

Frequently Asked Questions
