There should be 2 steel lines running parallel,inside your driver's side frame rails. They "stop",just in front of your rear axle. From there,they connect to the "pancake",with rubber tubing,(Heavier walls,to resist collapse). Thanks,51 ashton,for the switch location. Hopefully vacuum line is still connected. If not,you'll have to install a line from your intake manifold,to the switch. One line ,on the switch,connects to the manifold. The other two fittings attach to the frame lines. Button down-"'Lo,button up,'Hi. If that's not the case,simply reverse the lines at the "pancake". Hope this helps.
