Review on Partssquare 175 185 Electric Thermostat Temperature by David Miller

Good product concept. Please change the picture scheme. Another reviewer posted a nice diagram that much better identifies the setup. However, we recommend using a 30 or 40 amp relay. Maybe they thought they installed a 60 amp relay for the two fans. Use two separate 30A units for each fan. Don't use a 60A relay on your fan. You need to identify the numbers 86, 85, 87 30 to determine the connection of the device, the connection of the main power source - battery, ignition power and ground wire harness. The fan base goes to this, but should also go to the car with the ECM stick. You can also use ground to connect to the ECM ground wire used in this product. Also note that the wiring of the dual thermostat switch in a production car will need to be bypassed or you will need to figure out how to connect it. I use it on an '89 Camaro 305.
