I need a tach source to tie in the window switch for my nitrous setup.. I dont have the manual at the moment so I need some help here guys.. Car goes on the dyno tomorrow and i need a safety margin with the bottle.. What wire should I tap into to get what I need? Ive tried searcing on here but all I find is for early models not late.. ASAP help would be most appreciated!!
