Deutsch Autosport AS 37-Way Plug — Pin (Male) — Yellow Key (A)

The Deutsch Autosport AS 37-Way Plug Pin (Male) Connector with Yellow (A) Keying Insert — SKU: AS614-35PA is a professional MIL-spec-grade Deutsch Autosport AS series connector for high-density ECU main harness sub-connectors, full PDM wiring system interfaces, and primary race car loom separable joins in race cars and high-performance vehicles across Norway, Sweden, and Denmark. Configured as a free, cable-mounted plug half that mates with a fixed flange or inline receptacle — the movable, harness-side component that disconnects for component removal, harness separation, and servicing.

Deutsch Autosport AS 37-Way — 37-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 37-circuit configuration is used for ECU main harness sub-joins and PDM wiring system separable interfaces — one of the most widely-specified circuit counts in professional Scandinavian motorsport in professional motorsport builds throughout Scandinavia. Primary 37-circuit high-density shell — one of the most widely-specified as configurations in professional motorsport harness design.

Pin (Male) — 37-Circuit Contact Array

This is the pin half of the 37-way AS plug pair. Thirty-seven gold-plated pin contacts transfer the full 37-circuit load — the active array of one of the most widely-specified circuit counts in professional motorsport. 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.

Yellow Key (A) — Keying Position and Mis-Mate Prevention

Yellow A is the first key assigned in any Deutsch AS multi-connector keying plan — the default primary key that every harness builder reaches for when a harness includes multiple 37-circuit AS connectors at the same separation point. The Yellow A physical key tab on this plug half ensures it will only accept a matching Yellow A-keyed mating half — preventing cross-mating with any Blue B, Orange C, Green D, or Red N keyed half of the same circuit count. On a harness with two or more 37-circuit AS plug connectors at the same separation point, Yellow A identifies the primary pair — typically the most frequently accessed connector or the one carrying the most critical circuits. Professional harness builders across Norway, Sweden, and Denmark standardise on Yellow A as the primary key assignment for consistency across multiple builds and to simplify harness identification for mechanics and engineers at race events.

Plug Configuration — The Movable Cable-Mounted Connector Half

The AS plug is the free, cable-mounted half of the connector pair — it does not mount to a panel or chassis surface. The plug travels with the removable component or sub-harness and mates into a fixed receptacle (flange-mounted or inline) to complete the electrical circuit when the assembly is connected. This makes the plug the correct specification for engine-side harness connectors that must be disconnected for engine removal, dashboard harness sub-connectors that follow a removable dashboard assembly, removable subframe harness joins, and any other separable point where one connector half must be freely movable with a removable vehicle component.

The 37-circuit AS plug is used for high-density ECU main harness sub-connectors, full PDM wiring system interfaces, and primary race car loom separable joins across race cars and performance vehicles in Norway, Sweden, and Denmark. The plug’s free, unmounted format allows the harness builder to route the cable bundle freely from the removable component to the mating point without any chassis mounting constraint — then mate the plug directly into the fixed receptacle when the component is installed. The push-pull positive locking mechanism provides secure, vibration-resistant engagement that holds through race conditions while allowing intentional disconnection at every service interval.
