Ya it always starts for me, just like to complain (ie smoke). Pluggin it in is like putting a blankie on him when its cold 
I finally found it. It was in fact hidden behind the drivers side fog lamp tucked behind another wire.. Thanks for the tip there.. Now I can keep her warm this winter..Try looking behind the drivers sie tow hook. It will have a cover on the blades so its not easy to just feel for it. Its a black plug with a black cover.
