Why You Need This

Professional engine builds demand professional connections. This Bosch Junior Timer connector is the same specification used in OEM applications across European performance cars, providing the reliability your Haltech ECU setup demands. Whether you're building a custom harness for an LS swap, integrating additional sensors on a built RB26, or creating branch connections in a complex 2JZ setup, cheap aftermarket connectors will let you down when it matters most.

The 5-pin configuration is particularly useful for sensor clusters, timer relay connections, and auxiliary device wiring where multiple circuits need routing through a single, compact connector. We see this specification regularly in BMW applications, VAG performance builds, and custom motorsport installations where space is premium but connection integrity cannot be compromised. The sealed design prevents moisture ingress and corrosion, critical factors in engine bay environments where heat cycling and vibration constantly test electrical connections.

ECU & System Compatibility

Suitable for custom harness builds with all Haltech ECU families including Elite 550, 750, 1000, 1500, 2000, and 2500 series, plus Nexus R3, R5, and Rebel platforms. Commonly used in sensor integration, auxiliary output connections, and branch harness construction. Contact our technical team to confirm specific application requirements for your build.
