QR-03 with Electrical Data Connector

This collection contains QR-03 series quick-release steering wheel couplers with integrated 22-pin electrical data connectors, including male and female big couplers, 3-bolt variants, complete 22-pin connector sets and weld-on bosses. Components are supplied to connect steering wheel electrical circuits such as horn circuits, switches and paddle shifters while providing rapid wheel removal and reattachment for motorsport, automotive workshop and trade applications.

When selecting, verify shaft diameter or spline fit, the 3-bolt pattern, mating face dimensions and pin-out compatibility, and confirm connector retention method. Consider whether a weld-on or bolt-on mounting is required and plan harness routing with appropriate strain relief. Installation should be performed by a qualified technician or experienced fabricator and electrical continuity and secure fastening checked before vehicle use.
