I went a different way on my truck and it works great. I bought the style that is inside an adhesive strip, this does not touch metal, I have been looking for the pic but with 10,000+ on my Flikr it takes a few. Anyway it is about 24" long with a plastic end that attaches to the cable (it peels and sticks to the wood). I then ran it up through the hole in the bottom of the tool pan.
