Evo 8 ALT-Map Switching Harness (Standard Version)

This harness (when used with the Tephra v5 and up Stock ECU Reflash patches) allows the user to switch between 2 separate tunes on the fly with the flip of a switch while driving! The patch allows 2 separate settings for fuel,igntion timing,injector scaling and ECU controlled Boost levels. Great for users who switch between different fuel types (e85 vs. pump gas), alky kits enabled or disabled, or just two tunes at different boost levels.

The harness is 5 feet in length and comes with a discrete micro on/off switch, a 5mm L.E.D. indicator light with mounting bezel and a factory ECU pin connector is pre-installed for a factory fit into the ECU harness. A link to online diagrams and installation videos is supplied with each harness for ease of installation.
