I am replacing my auxiliary light switch of my car.
on the switch assembly, it has a positive, negative, and ground. I am replacing it with a pololu pushbutton power switch with an oem switch that is a momentary type.
Here is the switch: http://www.pololu.com/product/750/pictures
Positive to Vin Negative to Vout There are 4 grounds on this circuit board, so which one is the correct one to connect to the right ground?
Or am I completely wrong?
