No mismatched lights or out-of-place styling—it’s designed to feel like it came straight from the factory. The gauge also includes AutoMeter’s high-quality 1/8" NPT temperature sender, rated for data-grade performance, along with both 3/8" and 1/2" NPT adapters to make installation straightforward, even if you're using a transmission cooler manifold or tapping into the pan. It comes with everything you need for a clean install, including the wiring harness, mounting hardware, and detailed instructions. Whether you're pulling a trailer across the country or just working your truck hard day in and day out, this gauge gives you peace of mind—and helps you know when it’s time to back off before things get too hot.
