Yazaki 7123-6234-40 3-Way Female 58 Connectors X Type Housing

The Component: Genuine Yazaki high-performance sealed female flat contact receptacle connector plug housing. 58 Connectors X Type Heavy-Duty Sealed Series taxonomy / 3-position multi-row female casing / Standard Keying Profile (Industrial Gray Housing Shroud / Premium Heat-Stabilized PBT / Sealed Waterproof IP Rated / Multi-Row 3-Pole Grid Layout / Female High-Current Alternator, Fuel Pump, Window Regulator, and Main Power Distribution Loom Plug / Component Variant Alias: 7123-6234-40 / Global Order Reference: 7123623440).

Applications & Fitment: Engineered as a premium, high-current original equipment (OE) specification wire-to-wire or wire-to-device waterproof connection plug designed explicitly for heavy-load automotive power tracks, high-output auxiliary assemblies, and exterior-exposed chassis supply loops. This 3-pin female socket block is an absolute wiring loom repair, powertrain conversion, and commercial vehicle fleet harness reconstruction staple across prominent Japanese passenger, 4x4 utility, and transport platforms—most extensively integrated within factory Toyota, Lexus, Nissan, and Mitsubishi electrical system networks. It is standardly deployed across high-demand current transfer zones, serving as the main factory connector block for fuel pump assemblies, wiper motor linkages, electronic window regulators, and exterior lighting supply relays.

It features a robust, integrated mechanical top thumb-release locking clip mechanism, establishing a low-tolerance, positive engagement hold highly resilient to intense chassis vibrations, heavy under-chassis road spray, engine compartment fuel vapor exposure, and winter road salt tracking. Engineered to conform to rigid tier-1 automotive manufacturing guidelines, its compact heavy-wall internal grid cavities feature a 10.4mm horizontal pitch and 8.55mm row spacing designed to house and protect 6.3mm (.250 inch) nominal flat box female receptacle terminals (such as Yazaki 7116 series contacts). Paired with its matching independent rear TPA locking retainer, internal perimeter waterproofing rings, and individual single-wire rubber cable gates, it forms an absolute weather-tight, IP-rated barrier against environmental dirt tracking, moisture entry, and high-pressure steam washdowns. Highly critical service item for auto-electrical workshops, professional diagnostic garages, and commercial vehicle body builders overhauling corroded fuel pump plugs, burnt wiring sub-assemblies, or fractured chassis-side power feeds.
