The LED (+)(-) lead can only be used to connect to the MOSFET Source and Gate pins if the (-) and (+) are at zero volts vs. ground when the LED is off. I don't think this will be true. I suspect that they will be at
12 to 13 for (+) and something random between 0.5 and 10.5 when off and
12 to 13 for (+) when and 10.5 to 11.5 when on
Remember, measure from chassis ground to the pin in the DC voltage mode and report values.
The LED alarm light LED is at 0 volts when it's off, and 1.5 V when it's in alarm state.
The Strip LED (12V) has 12VDC on the (+) lead at all times.
