[Prerunner1982]

not sure about your set up, my 82 had a box on the drivers side fender, the speedo cable from the gauge goes to the box, then another speedo cable goes to the trans. There is a diaphram that mounts to the back of the intake manifold that connects to the carb, it is vac. operated.. as far as the hoses i dont have a clue, but those should be the 2 main components...
