Subaru Stand-alone Interface Board Light

The Subaru interface board is an all in one interface comprising most of the fuses, relays, connectors, diagnostics. indicators lamps and even an onboard OBDII diagnostic port to interface to your Subaru stand alone wiring harness.
This board is a scaled down econmical version of the Subaru Interface box, which was sometimes overkill on a basic non-canbus harness.
It is designed to replace the loose modules, relays and connectors and house them all in one board, designed to mount on top of the engine ECU. This interface board does NOT include fuses and radiator fan relays.
The interface board also includes add on options such as a Canbus Emulator.
"Test Mode" and "Read Memory" subaru connectos are replaced with on-board toggle switches. A toggle switch selects between constant OBDII power and switched OBDII power. This enables an OBDII scanner (or bluetooth module) to be able to be plugged into the OBDII port permanently without flatening the vehicle battery.
 
Designed to work on just about all OEM Subaru EFI wiring systems, from the 1990s EJ22 all the way to current model Canbus/electronic throttle systems, with provision for powering the Subaru automatic transmission.
 
The interface shaves up to several hours off the harness modification time and also simplifies and speeds up the electrical install to the vehicle.
 
The unit comes with moutning screws for mounting to the ECU. The unit does not come with relays, as it is intended for the Subaru relays to be re-used from the donor harness. The relays are standard "Micro ISO" relays.
The canbus emulator is available as options at time of ordering.
