Question on PWM of LED's in dash lighting
I have a question on wiring this pwm module for my dash LED's to control dimming. It is my understanding that the PWM takes place on the negative of the output.
Here is the unit and suggested wiring.
As you can see both input and output are isolated from each other.
My question is that I cannot easily seperate the two negatives, as I have a 1958 thunderbird, which utilizes the metal dash as the return (negative).
Can I tie both negatives to the metal, without harming this unit, and will it still function properly. There is no trouble keeping both positives seperate.
