The Haltech Elite 1500 adaptor harness ECU kit is a harnessed installation option for the Elite 1500 controller, intended to simplify wiring in custom or retrofit engine management projects. By converting the standalone ECU into a plug‑in harness configuration it reduces installation complexity and helps tuners achieve a neater, more serviceable wiring layout without asserting unlisted features.
