Haltech

Haltech's range here is wiring and connection parts, with a small group of gauges. Nearly all of it is harnesses, cables and connectors, so the decision is about which Haltech system you are connecting and which engine or device sits at the other end.

There is no vehicle list for this brand. Titles name the Haltech product line and the target instead. The lines in the titles are Elite, Nexus and Nexus Rebel. Examples are Elite 1000 and 1500 or 2000 and 2500 plug-and-play adaptor harnesses, a Nexus Rebel harness for an LS engine with a T56 transmission, and a Nexus Rebel main engine wiring harness for a JZ engine.

Pick the harness by the Haltech unit first, then by the engine. A plug-and-play adaptor harness lets an Elite connect to a factory plug without cutting the loom, and a terminated engine wiring harness is a full main harness that is already finished at the engine end. Universal parts, such as the IO expansion harness, are sold by length, in metres and feet.

The accessory parts include a CAN cable with DTM connectors, a wideband adaptor harness for an LSU4.9 sensor, and loose Bosch-style connector plugs and pins for building your own leads. Check the connector name in the title before ordering, since DTM, Bosch and other types are not interchangeable.

For wiring parts from other makers, see wiring and electrical, and for gauge parts see gauges. Each product page lists what it connects and, where relevant, the years, makes and models it fits.
