Wiring Specialties LS3 Gen IV 58x DBW Wiring Harness for FRS/BRZ/86 - CANBUS PRO SERIES


Looking for a Plug and Play solution for your LS V8 swapped FRS/BRZ/86? The Wiring Specialties Pro Series Harness is the solution for saving you time and headache when wiring up your engine swap.

This harness includes full CANbus integration so you can forget about those electrical gremlins once and for all. This harness and add-on CAN module allows the use and function of the OEM gauges, ABS and EPAS electric steering! It is made for a typical GM LS3 "E38" engine control module (not included).

This harness is perfect for a Scion FRS (2012-2016) / Subaru BRZ (2012+) / Toyota 86 (2012+) with an LS3 engine swap. This harness was developed in house on an actual LS3 engine to ensure a perfect fit to all engine connections.

  • Plug and play installation into the chassis using a completely new Wiring Specialties PRO harness (no cutting or modifying factory wiring)
  • Gauge functionality with tach, coolant temp, CEL, Speedometer, traction lights etc - fully functional
  • Supported A/C functionality with stock Toyota lines and pressure sensor
  • Dual Fan supported through factory wiring (for both OEM and Aftermarket ECUs)
  • Supports proper Power Steering operation (variable if ABS controller is retained)
  • Push-button START supported on Premium models
  • Proper Fuel Level gauge functionality

This kit was ordered for an in-house 86 LS swap but we changed direction and need to go with a much more expensive motorsports ECU and harness. Instead of taking weeks to be built and paying top dollar, you can get this today from Vorshlag with the options shown below
