Installation Details

This kit is pretty much plug-and-play, but you'll need to disconnect some factory fuel lines. It???s best to take your time or let a pro handle it if you???re not comfortable. The harness is cut to the right lengths for a clean, factory-like installation, so no worries there.

Engine Compatibility

If you've got a 2015-2021 VW MK7 or Audi 8V with a 2.0T EA888 Gen 3 engine, this harness is for you. Just a heads up, it won???t do its magic without the matching IE TrueFlex ethanol tune. Tuning is available for specific model years, and they???re adding more all the time. If your model year isn???t supported yet, you can still install the kit. The stock ECU will ignore the harness input until you flash the tune, but don???t run any ethanol without that TrueFlex tune in place.
