Thanks for the info ! I'll be making myself a set of these for sure. A week or two ago I was under my bug and the previous owner had cut into the wire for the radiator temp sensor and I had to replace that wire due to corrosion where he left it exposed. I took the wire from my parts car and put it into my plug and made a good splice. If I had the tool I wouldn't have spent an hour with a tiny eyeglass screwdriver . Tks!
