Why You Need This

Complex engine builds demand more I/O than any ECU's primary harness can provide. Whether you're running a compound turbo setup with multiple wastegates, a methanol injection system requiring precise control, or a comprehensive data logging array with additional temperature and pressure sensors, the IC-7 auxiliary connector handles the overflow. Without proper auxiliary expansion, builders either compromise their sensor package or resort to splicing into the main harness — both scenarios that limit performance potential or create reliability issues down the line.

We see this constantly in high-end LS swap projects where customers want to retain factory-level refinement while adding serious performance hardware. A typical build might need auxiliary outputs for boost controllers, staged injection, cooling fans, and data acquisition sensors. The IC-7 kit provides those connections through Haltech's engineered interface rather than aftermarket splicing that can introduce voltage drops or connection failures. The 300mm length is perfectly sized for most engine bay routing without excess cable management headaches.

ECU & System Compatibility

Designed specifically for Haltech Elite PRO ECUs with IC-7 auxiliary ports. This includes the Elite 1500 PRO, Elite 2000 PRO, and Elite 2500 PRO models. The direct plug-in design ensures secure connection and proper pin assignment for auxiliary functions.
