📦 What’s included
- 1× NTC temperature sensor — 1/8 NPT threaded probe with two braided lead wires (0°C to 150°C)
- 1× 2-wire NTC wiring loom — 1.5 m TXL pigtail with bullet connectors at the sensor end
Does not include a REVVGAUGE unit.
⚡ Why this sensor
- Built for REVVGAUGE — 2-wire NTC type, compatible with REVVGAUGE analog inputs (100 Ω to 50 kΩ)
- Coolant & oil ready — 1/8 NPT fit suits common coolant ports, radiator bosses, and oil galleries
- Matched loom included — no hunting for the right pigtail; bullet connectors mate directly with the sensor leads
- Configure in the app — set up your NTC channel and temperature scaling in the REVVGAUGE app
- Durable leads — braided sensor wires and automotive TXL loom wire for engine-bay use

🔧 Installation
Install the 1/8 NPT sensor in your coolant passage, radiator boss, or suitable fitting. Connect the loom’s bullet connectors to the sensor leads — green (NTC+) to the male bullet, black (NTC−) to the female bullet.
Route the loom to your REVVGAUGE harness. Terminate the harness end at an available AIN pin and pin 14 GND on your Molex connector (use a pre-crimped green wire from your standard loom for the analog input if needed).
Configure the channel as an NTC sensor in the REVVGAUGE app. Use the sensor manufacturer’s resistance–temperature data for accurate readings if required.
Suitable for coolant temperature monitoring. Can also be used for oil temperature in a compatible 1/8 NPT location.
