Elite 550 + Premium Universal Wire-in Harness Kit (HT-150404)

Full standalone control of fuel, ignition and boost, at the entry price.

The Haltech Elite 550 + Premium Universal Wire-in Harness Kit is the Elite 550 ECU with the Premium universal wire-in harness. The Elite 550 is Haltech's entry-level single-connector Elite: full control of fuel, ignition and boost for a basic four-cylinder, V8 or two-rotor build, with flex fuel and on-board logging included.

The universal wire-in harness has the ECU connectors fitted at one end and colour-coded, labelled flying leads at the other, matched to the Haltech wiring diagram, so a from-scratch install is a matter of cutting to length and terminating. The Premium harness adds a firewall grommet and a moulded Haltech fuse and relay box, so power distribution is handled in the kit.
