Deutsch Autosport AS 79-Way Inline — Socket (Female) — Yellow Key (A)
The Deutsch Autosport AS 79-Way Inline Socket (Female) Connector with Yellow (A) Keying Insert — SKU: AS120-35SA is a professional MIL-spec-grade motorsport connector for near-maximum-density full race car loom separable joins and primary ECU main harness interfaces in race cars and performance vehicles across Norway, Sweden, and Denmark. This socket half is the receptacle side — the gold-plated socket terminals receive the incoming pin contacts from the corresponding pin (pin) half, completing all 79 circuit connections when the connector is engaged and locked. Configured as an inline connector — in-line harness separable join — both halves are free, cable-mounted connectors within the wire run.
Deutsch Autosport AS — 79-circuit Inline Connector
The Deutsch AS series is the standard Autosport circular connector format for professional motorsport — providing the 79-circuit capacity required for this application in a robust aluminium alloy shell with push-pull positive locking, gold-plated contacts, and full MIL-spec environmental sealing for race-condition reliability. One of the highest circuit counts in the as inline range — used where the complete ecu harness, pdm wiring, and ancillary circuits must cross a single inline connector interface in a full professional race car loom build. The 79-circuit AS inline is specified for the most complex full race car loom separable joins — where virtually the entire vehicle electrical system must be separated at a single inline connector point, such as engine bay to chassis harness splits in purpose-built race cars.
Yellow Key (A) — The first standard keying position in the deutsch as system
As the the first standard keying position in the Deutsch AS system, the Yellow A key is assigned to the most frequently accessed or most critical connector pair in a multi-connector harness. When a harness includes multiple AS 79-way inline connectors at the same separation point — for example, splitting a complex ECU loom into two parallel bundles of 79 circuits each — Yellow A identifies the first (primary) pair. Yellow A is the most widely specified starting key — assigned to the primary connector when multiple same-circuit-count AS connectors appear on a single harness. A Yellow A-keyed connector will only mate with another Yellow A-keyed half of the same circuit count, preventing cross-mating between connectors during initial installation and subsequent harness servicing.
Contact Type — Socket (Female)
This listing is for the socket half of the 79-way AS inline pair — the receptacle contact half — the socket terminals receive and make contact with the incoming pin terminals when the connector is mated, completing the electrical circuit across the separable join. The corresponding pin half of the same circuit count and key colour is required to complete the mated connector pair. AS contacts are ordered separately — select the correct contact part number for your wire gauge and current requirements.
