Run your NASCAR-wired helmet in an IMSA-harness car — no rewiring.

Switching series or jumping into a different car? This 6-inch adapter cable bridges a NASCAR-style helmet (3-conductor) to an IMSA car harness (4-conductor), so your existing helmet just plugs in and works. Built and tested by Speedcom, the folks who've wired race teams since 1996.

  • Keeps your current helmet — no need to rewire or buy a second one
  • Plug-and-play: helmet in, harness out, done
  • Full IMSA 4-conductor signal for clean driver/crew comms
  • Rugged molded connectors and an abrasion-resistant polyurethane jacket — built for the car, not the bench

Works with: any helmet with NASCAR-standard 3-conductor wiring, connecting to IMSA car harnesses running Motorola, Vertex, Kenwood, and compatible radio systems.

Specs: 6 in (152 mm) · 22 AWG stranded copper · molded automotive-grade connectors · polyurethane jacket · −40°C to +85°C.
