The FR-S FA20 is built for drivers, and every engine improvement starts with being able to tune it properly.
The 2016 Scion FR-S FA20 is a well-sorted platform with a loyal following, but the factory ECU limits what's accessible for serious modifications. The Tuned By Shawn Boomslang PNP Wiring Harness for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.

The Details
Built specifically for this vehicle's connector layout with OEM-spec connectors and correct wire gauge throughout.
