Honda 3-Pin TPS / MAP / IACV Connector & Terminal Kit (Round Style)

OEM-Style Round 3-Pin Sensor Connector for Honda Engine Harnesses

The Honda 3-Pin TPS / MAP / IACV Connector & Terminal Kit is designed for professional harness repair, engine swaps, and custom wiring builds using round-style 3-pin Honda sensor connectors. These connectors are commonly used on throttle position sensors (TPS), manifold absolute pressure sensors (MAP), idle air control valves (IACV), and select auxiliary engine sensors on non K-Series Honda platforms.

This kit provides a clean, OEM-style solution for replacing damaged connectors or building custom engine harnesses with proper terminal retention and reliable electrical contact.

Designed for Professional & Motorsport Wiring Applications

Accurate sensor signal integrity is critical for proper ECU operation, drivability, and tuning. This connector kit is suitable for street, track, and motorsport environments, offering durable construction and secure terminal engagement when installed correctly.

The round 3-pin design is widely used across Honda OBD0, OBD1, and early OBD2 applications and remains a staple in B-series, D-series, H-series, and F-series wiring.

Correct Terminal Support with Spare Included

This connector housing accepts terminals compatible with 22–16 AWG wiring, allowing flexibility for signal, power, and ground circuits depending on sensor application.

Each kit includes an extra terminal, providing margin for installation errors or future service without delaying a build.

Common Sensor Applications

This connector kit is commonly used for:

• Throttle Position Sensor (TPS)

• Manifold Absolute Pressure (MAP) sensor

• Idle Air Control Valve (IACV)

• Select Honda engine management sensors using round 3-pin connectors

Commonly found on Civic, Integra, CRX, Prelude, Accord, and other Honda platforms depending on engine and year.

What’s Included

• 1× Honda Round 3-Pin Connector Housing

• 4× Terminals (22–16 AWG compatible, 1 spare included)

Please reference product photos to confirm connector style. This listing is for the round 3-pin Honda connector, not K-Series style connectors.

Installation Notes

Proper open-barrel crimping tools are required for correct terminal installation. Professional wiring knowledge is recommended to ensure correct pin orientation and long-term reliability.

Incorrect sensor wiring may result in drivability issues or ECU faults.
