TYCO AMP 174982-2 / 174984-2 — 8-Pin Sealed Waterproof Automotive Connector for Denso Systems
Part Numbers: 174982-2 (female housing) / 174984-2 (male housing)
Manufacturer: TE Connectivity (formerly TYCO AMP)
Denso is the world's second-largest automotive supplier, and its fuel injection systems, ignition modules, alternators, and ABS sensors are found in virtually every Toyota, Lexus, Honda, Subaru, Mazda, and Mitsubishi vehicle built in the last three decades. The 8-pin sealed connector 174982-2 / 174984-2 is a critical interface in Denso's wiring architecture — used wherever a fully sealed, vibration-proof, multi-pin connection is required in an under-hood or underbody environment. When this connector degrades, the consequences range from intermittent sensor faults and ECU error codes to complete system failure. This genuine TE Connectivity / TYCO AMP specification replacement restores the OEM-grade sealed connection your Denso system demands.

Why Sealed Connectors Fail — and Why OEM-Spec Replacement Matters
The Superseal 1.5 series was designed by AMP (now TE Connectivity) specifically for automotive environments where moisture, fuel vapour, road salt, and thermal cycling are constant threats. Despite this, the individual wire seals harden and crack over time, the interface seal loses compression, and terminal corrosion develops behind the seal face — invisible until a fault code appears. Generic non-sealed replacements are not appropriate for these applications; only a fully sealed connector maintains the IP67 integrity required by Denso's system design. Technicians in the UK, Australia, New Zealand, Japan, and North America consistently specify OEM-equivalent sealed connectors for Denso harness repairs to avoid repeat failures.
Global Market & Regional Notes
Denso-equipped vehicles are among the most common on roads worldwide. This connector is in active demand across Japan, Australia, New Zealand, UK, USA, Canada, Southeast Asia (Thailand, Indonesia, Malaysia, Philippines), the Middle East (UAE, Saudi Arabia, Kuwait), and South Africa — wherever Toyota, Honda, Subaru, and Mitsubishi vehicles are serviced. The TE Connectivity / TYCO AMP Superseal 1.5 series is also widely used in marine, agricultural, and industrial equipment wiring harnesses, making this connector a versatile stock item for auto electricians and harness repair specialists.
Installation Notes
- Use a Superseal 1.5 terminal extraction tool — do not use a flat-blade screwdriver, which damages the terminal locking lance
- Inspect individual wire seals before re-use; replace if cracked or hardened
- Apply a small amount of dielectric grease to the interface seal face before mating
- Ensure wire seals are fully seated before inserting terminals — an unseated wire seal will compromise IP67 rating
- Confirm terminal crimp height with a calibrated crimp tool (TE 539635-1 or equivalent)
