Installation was fairly smooth, and the adapter integrates perfectly with the SmarTemp controller. Make sure you look at the picture on the website to what connector goes where, it’s a little bit of an octopus. The harness feels durable and well-constructed, ensuring a reliable connection. Overall, it makes installing the SmarTemp 3.0 system fairly easy and hassle-free. Hardest part was running the wires to get the thermostat where I wanted it. Highly recommended!
