Subaru & Toyota 3-Pin Alternator Connector Kit (HX 090 Series)

Tired of the "Battery" light flickering on your dash? The HX 090 Sealed Series 3-pin connector is a primary failure point on many Subaru and Toyota charging systems. High engine bay temperatures eventually turn the factory plastic brittle, causing the locking tab to snap or the internal terminal seats to fail.

Unlike many aftermarket options, this connector is confirmed to work with your OEM terminals. This means if your wiring is still healthy but the plastic housing is smashed, you can simply swap the housing over without the need to cut and solder—saving you time and maintaining the integrity of your factory loom.

• Subaru: Fits a wide range of factory alternators.

Installation

• Repair Tip: If your existing terminals are in good condition, you can depin your old connector and slide them directly into this new housing.
