I have to agree. I tried a positap on that wire, and it didn't make a very good connection for me. I ended up just stripping about 3/4" of the outer coating, wrapping the reverse wire around it and soldered/wrapped it. I realize this is a much more permanent connection, but I'm not planning on getting rid of my truck.posi taps, t-taps, scotch locks are all junk, buy a set of wire strippers for almost the same price and do it right.
