This plug-and-play adapter harness connects an existing Sniper 1 wiring harness to a Sniper 2 throttle body, eliminating the need to rewire the vehicle when upgrading. It works with any Sniper 2 system that isn't equipped with a Power Distribution Module (PDM): remove the Sniper EFI throttle body, unplug the connectors, plug in the adapter harness, cycle the ignition key, and run the setup wizard on the display of choice.
Specifications:
- Part Type: Engine Control Module (ECM) Wiring Harness
- Part Number: 558-489
The wiring harness included with the Sniper 2 kit is not used with this adapter — it's intended to work with the original Sniper EFI wiring harness paired with the new Sniper 2 EFI throttle body. Sniper 2 brings a next-generation ECU with improved RF noise and interference resistance, a rear-exiting "hidden harness" for a clean appearance, and a mil-spec M8 positive-lock CAN connector.
