    Hey guys

    I am installing a navigation radio in my 2004 GMC savanna and I need to locate the speed sensor wire along with the reverse light wire. A friend of mine told me it would be probably be a green wire located under the dash, but I can't seem to find it:neutral:. Any help would be greatly appreciated.
