My daughter has been wanting a gauge to know the outside temp for her 2002 SR5. I’m a stock/OEM kinda guy so I wasn’t wanting to modify the dash much. Here’s what I bought. It measures inside and outside temp.

IS Icstation Digital Thermometer
Amazon.com : IS Icstation Digital Thermometer, Car Auto Temperature Gauge Sensor, DC 4-28V Fahrenheit Dual Display, Monitor with 2 NTC Waterproof Probes for Aquarium Vehicle Fish Tank : Pet Supplies

I tapped the fuse box with this:

Nilight Fuse Holder Add-a-circuit Fuse TAP Adapter
Amazon.com: Nilight Fuse Holder Add-a-circuit Fuse TAP Adapter Mini ATM APM Blade Fuse Holder-10 Pack , 2 years Warranty: Automotive

The vehicle has 3 power ports on the dash, which is a lot, so I installed the gauge in place of one of the outlets. I cut the rectangular opening with a dremel. I kind of buggered up the opening because the dremel mostly melted the plastic instead of cutting. There’s probably a better way. In the space below, I installed a USB/aux port for the head unit

The I put the outside temp probe at the grill. The probe lead that came with the gauge wasn’t long enough so I spliced in some wire and ran it through the firewall with the hood latch cable and wire harness.

Here are some pics

Looks like the pics didn’t make it. I’ll try again...

Very nice ! If you get some heat bleed off from the engine try putting the sensor in the air box.

Awesome find and mod. Will that fit where the emergency flasher button is?
I always hated it in the middle of the dash and want to move it somewhere else.

nice clean job. been thinking of something like this for a while.

Too big for that location. It’s more similar in size to the clock.
