The board-end connector solders or press-fits directly to the PCB; the mating harness plug connects the external wire harness to the ECU. These connectors are used in engine control modules (ECM), transmission control modules (TCM), ABS\/ESC modules, and body control modules (BCM) across a wide range of vehicle platforms. The waterproof design maintains IP67 sealing at the ECU housing penetration point.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 1437290 (TE Connectivity \/ AMP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Counts:\u003c\/strong\u003e 26-pin and 34-pin configurations (select above)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type:\u003c\/strong\u003e Board-end (PCB solder or press-fit) + panel mount flange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWaterproof Rating:\u003c\/strong\u003e IP67 (mated with harness plug)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Copper alloy, gold-plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material:\u003c\/strong\u003e PBT (polybutylene terephthalate), flame retardant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -40°C to +125°C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 12V \/ 24V DC automotive systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1, 5, or 20 pieces (select above)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBoard-End vs Harness-End Connectors — Understanding ECU Connector Pairs\u003c\/h3\u003e\n\u003cp\u003eECU connectors always come in matched pairs:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoard-end (this product):\u003c\/strong\u003e Mounts on the ECU PCB inside the module housing.

The connector part number (e.g., 1437290) is typically listed in the ECU technical documentation. Alternatively, count the pins and measure the connector body dimensions to cross-reference against TE Connectivity’s connector catalog.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"Can I replace a damaged board-end ECU connector?\"\u003c\/em\u003e — Yes, but it requires ECU disassembly, desoldering the damaged connector, and soldering the replacement. This requires SMD rework skills and equipment. For most users, replacing the harness-end pigtail is the simpler repair — the board-end connector is only replaced when the ECU PCB itself is being repaired or rebuilt.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"What causes ECU connector failures?\"\u003c\/em\u003e — The most common causes: (1) corrosion from moisture ingress — damaged housing seal or missing connector seal allows water into the connector cavity; (2) terminal backout — damaged locking lances allow terminals to push back under vibration; (3) fretting corrosion — micro-movement between mated contacts in high-vibration environments causes oxide buildup and increased resistance.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cem\u003e\"What contact cleaner is safe for ECU connectors?\"\u003c\/em\u003e — Use electronics-grade contact cleaner (e.g., Caig DeoxIT D5) applied sparingly with a fine brush or applicator. Do not spray directly into the connector — excess cleaner can wash lubricant from the contact surfaces and damage plastic housing materials. Allow to dry completely before reconnecting.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eECU repair:\u003c\/strong\u003e Replacing damaged board-end connectors on engine management modules during ECU rebuild\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCustom ECU builds:\u003c\/strong\u003e Installing OEM-compatible connectors on custom or aftermarket ECU boards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotorsport:\u003c\/strong\u003e Building OEM-compatible harness interfaces for standalone ECU installations\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomotive electronics repair:\u003c\/strong\u003e TCM, ABS module, BCM connector replacement during module refurbishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e1, 5, or 20 pieces (select above) — AMP type board-end ECU connector, pin count as selected.
