okay so i have these led strips in my van I'm trying to run straight off the batteries. So I want to run power from the house batteries to a couple toggle switches. I know the positive is in the middle of the connector end and the negative is the outlying piece so I can cut it open and ohm it out to find which is which. But my question is, is it just that simple? What about the diode? Do I splice it with it or cut that out? I tried google but all I'm finding is people changing the ends, not actually getting rid of the AC/DC converter.
