Plugs and Pins Only - Suit Idle Air Motor 2 Screw Style

Overview

Essential connector hardware for integrating 2-screw idle air control motors with Haltech ECU systems. These genuine Haltech plugs and pins ensure reliable electrical connections for precise idle control in EFI conversions and engine swaps where OEM connectors don't match your new management system.

Technical Specifications

• Part Number: HT-020307
• Application: 2-screw style idle air control motors
• Contents: Connector plugs and terminal pins
• Compatibility: Haltech ECU wiring harnesses

Why You Need This

Idle air control integration is where many EFI conversions fall down — bodged connections create erratic idle, stalling, and failed MOTs. The 2-screw IAC motor style is common on Honda B-series, Toyota 4A-GE, and many European applications, but their OEM connectors won't mate with Haltech harnesses without proper interface hardware. These genuine Haltech plugs and pins create the correct electrical pathway for your ECU to command precise idle air bypass.

We see countless builds where customers have attempted makeshift connections using generic spade terminals or crimped joints that work initially but fail under vibration or moisture ingress. In throttle body conversions on classic Minis running Honda B16 swaps, or Escort Cosworth projects retaining factory IAC hardware, proper connector integrity is critical for stable closed-loop idle control. These components ensure your Haltech ECU can accurately control idle speed across all operating conditions, from cold start enrichment through to hot idle compensation.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range when interfacing 2-screw style idle air control motors. Most commonly required in Elite 550/750 applications and Nexus R3 conversions where existing IAC hardware is retained.
