Noise Filter on 12v Power Point
I found a noise filter that the p/o hooked up to the the 12v power point on my radio bezel. I don't know why it is hooked up and want to get your ideas. It is from radio shack and has supplied power going in, and out back to the power point. Does it serve a good enough purpose to keep? or should I just wire it back to the way it was stock? I was wired in with wire nuts and electrical tape which scare me.
