I just ordered two of these from Jegs http://www.jegs.com/i/JEGS+Performan...11063/10002/-1 About a week ago I found out one of my bosch 044 s wasnt running due to a faulty relay and I didn't know it .I'm gonna pull a wire from the hot sides of both pumps to these up front where I can see them one for each pump. That way I'll know both pumps have power all the time .
