GlowShift’s Replacement Ambient Air Temperature Gauge Sensor Harness will replace the existing harness used on your 10 Color Digital Ambient Air Temperature Gauge. This harness enables you to take outside air temperature readings by connecting to the gauge’s Electronic Ambient Temperature Sensor. Featuring a length of 18’, GlowShift’s ambient air temperature sensor harness has a 3 pin connector with black and white wires attached. A 2 blade female connector is also featured which securely plugs into the sensor. Please note that this harness is only compatible with 10 Color Digital Ambient Air Temperature Gauges (GS-TCD24). With a few simple connections your replacement ambient air temp gauge sensor harness will be in place so that you can continue to take effective readings. GlowShift also includes free lifetime tech support and a one-year limited warranty with each ambient air temp sensor harness purchase.
