These are harnesses for the use of Haltechs Elite 1500 and 2500 units.
  - The Elite has full control of fuel and ignition timing.
  - Choose your specific vehicle in the dropdown menu and then select the Elite unit you wish to use.
  - Eight cylinder engines are best suited to the Elite 2500 to retain sequential injection and direct fire ignition.
  - Six cylinder engines are best suited to the Elite 2500 to retain sequential injection and direct fire ignition.
  - Four cylinder engines can be operated with any of the available Elite units and still retain sequential injection and direct fire ignition.
  - In some instances, the factory ECU remains in place to control dash gauges, drive-by-wire throttle systems, and other amenities.
  - Dodge/Hyundai/Kia applications include a mandatory aftermarket coil driver wired into the Boomslang harness.
  - Fully plug and play. Easy to install. Easy to uninstall.
  - We fabricate the sub-harnesses. No cores needed.
  - Saves time, hard-wiring costs, and your factory wire harness.
