More Data. Cleaner Wiring.
The iWire TGV to Temperature Sensor Adapter Harness makes it simple to add fuel temperature, air temperature, or other compatible temperature data to your Subaru.
Adding additional sensors shouldn't mean building a custom harness from scratch. The iWire TGV to Temperature Sensor Adapter Harness provides a clean, prewired connection between the factory TGV wiring and a compatible temperature sensor.
It's also a great solution for standalone ECU applications where additional temperature data can improve monitoring, tuning, datalogging, diagnostics, and engine protection strategies. Choose your vehicle, harness length, and sensor configuration to get the setup that fits your engine bay and build.
Use Your Existing TGV Wiring
When the factory TGV system is no longer in use, the existing wiring can provide a clean path for adding temperature sensor inputs without running an entirely new harness through the engine bay.
Instead of sourcing connectors, terminals, and wire or building the adapter yourself, the harness arrives configured for the vehicle and sensor selected at the time of ordering.
Ideal for Standalone ECU Applications
Standalone ECUs make it possible to monitor more of what is happening with the vehicle, but adding those sensors still requires the right wiring. This adapter makes it easier to add useful data such as fuel or air temperature while keeping the installation clean and organized.
Additional temperature data can be used for tuning, datalogging, diagnostics, engine protection strategies, and a better overall understanding of how the vehicle is performing.
Built to iWire Spec for the Engine Bay
Every harness is built to iWire specifications using military-grade materials selected to handle the heat, vibration, moisture, and harsh conditions found in the engine bay.
The result is a purpose-built wiring solution designed for long-term reliability in an environment where ordinary wiring materials may not hold up.
