Okay i am installing my white gauges, and i have read that it is easier to get wire tappers, to tap into the brown wire for my power to the gauges, But i went to Sears Hardware and asked them if they sold them, and they told me they never heard of tappers for what i am attepmting to do, but they said that the sell something along the same idea, but that they are made for tapping into phone lines and so forth. Are these the same thing, or are they different? Thanks for the help!!!!!
