this part is built tough and works great. the wireing part is a little tricky and you might need to but some male and female connectors and some fusable links to get this installed correctly. but now my jeep doesnt overheat. i have 2 electric fans on my jeep . i set one to turn on at 100F and the other turns on at 200F. havent had any problems and its been over 100F and humid out.
