The Bell Female-to-Female Nexus Connection Cable (BEL2140071) is a flexible interconnect cable that allows Peltor-compatible intercom amplifiers, helmets and headsets to connect with Stilo WRC amplifier systems, helmets and headsets. In practical terms, this is an adapter cable for rally teams where the driver’s helmet uses one manufacturer’s connector standard and the co-driver’s uses another, or where an older amplifier is being used with a newer helmet wiring loom.
The Nexus connector is Bell’s and Zeronoise’s standard for intercom wiring in their helmet and amplifier range. Stilo WRC systems use a different physical connector and are common in rally co-driver setups. This female-to-female cable bridges the two standards without requiring the wiring on either side to be modified.
Intercom systems are connector-specific; fitting the wrong cable between components produces either no audio or degraded signal. If you are building a new system or adding a cable to an existing setup and want to confirm the correct cable for your amplifier and helmet combination, tell us the model numbers of both before ordering.
