    I've got a quick question that hopefully someone can help me out with. I've decided I want to install an LED in my case that will light up when my pump is NOT on. A warning light of sorts. I'm using the swiftech pump relay kit wired to my pump, and I was wondering if anyone knew of an easy way to wire this up. Any help would be greatly appreciated. Thanks...

    thanks, I'm still new to the forums so I guess mistakes are to be expected.

    If you have a DT switch on the pump relay you can use the off position to run a led.

    Code:
                OFF  /o-----led/resistor--------0v
12v------------o/
            ON    o-------Pump---------0v
    But, if you want the alarm light when the pump is supposed to be on but the motor's foobarred, gets a bit trickier. :confused: May need a flow sensor or a temperature alarm.
