Deutsch Autosport AS 79-Way Flange — Pin (Male) — Red Key (N)
The Deutsch Autosport AS 79-Way Flange Pin (Male) Connector with Red (N) Keying Insert — SKU: AS020-35PN is a professional MIL-spec-grade Deutsch Autosport AS series connector for near-maximum-density full race car loom separable joins and primary ECU main harness interfaces in race cars and high-performance vehicles across Norway, Sweden, and Denmark. Configured as a panel-mounted flange connector that bolts permanently to a chassis panel, bulkhead, or firewall — the fixed, chassis-anchored half that the cable-side plug mates into.
Deutsch Autosport AS 79-Way — 79-circuit Circuit Configuration
The Deutsch Autosport AS series is the professional standard circular connector format for motorsport wiring — aluminium alloy shell, gold-plated contacts, positive push-pull locking, and full MIL-spec environmental sealing for race-condition reliability. The 79-circuit configuration is used for complete ECU harness, PDM wiring, and ancillary circuits crossing a single connector in a full professional race car loom build in professional motorsport builds throughout Scandinavia. Near-maximum density 79-circuit shell — one of the highest circuit count configurations in the as series.
Pin (Male) — 79-Circuit Contact Array
This is the pin half of the 79-way AS flange pair. Seventy-nine pin contacts transfer seventy-nine individual circuits — the near-maximum density active array of one of the highest circuit count connectors in the AS series. The corresponding socket half of the same circuit count and key colour completes the mated pair — both halves are required. AS contacts are ordered separately; select the correct contact part number for your wire gauge and current requirements.
Red Key (N) — Keying Position and Mis-Mate Prevention
Red N is the neutral (non-keyed) specification — the correct choice when only a single 79-circuit AS flange is used at this separation point and no adjacent same-size connector creates a mis-mate risk. An N-keyed half mates with any other N-keyed half of the same circuit count, keeping the connector specification simple and straightforward for single-pair 79-circuit AS applications. Red N is also commonly used on initial harness prototype builds before the final keying strategy is confirmed, on harnesses where each AS connector is a unique circuit count (eliminating any possibility of mis-mating by design), and on any motorsport harness build in Norway, Sweden, or Denmark where keyed mis-mate prevention between same-circuit-count connectors is not required at this particular separation point.
Flange Configuration — Panel-Mounted Fixed Connector Point
The AS flange connector mounts permanently to a chassis panel, bulkhead, or firewall using the integrated mounting flange holes — creating a fixed 79-circuit connector point anchored to the vehicle structure. Once bolted in position, the flange remains in place throughout the vehicle’s service life while the matching plug half is mated and unmated repeatedly for component installation, removal, and servicing without disturbing the chassis-side connection.
The 79-circuit AS flange is used for near-maximum-density full race car loom separable joins and primary ECU main harness interfaces across race cars and performance vehicles in Norway, Sweden, and Denmark. Flange connectors are the standard specification at firewall primary harness separation points, engine bay bulkhead connectors, chassis rail panel interfaces, and any harness separation point that aligns with a structural surface suitable for mounting. The fixed flange provides a permanent, precisely-located connector point that makes harness re-mating fast and repeatable at every race event service interval.
