The two lines off of the stock p/s pump are used to up the idle speed when steering effort is needed. I now run a pump w/o such a vacuum switch, so I just plugged one of the lines and hooked it to the other fitting on the idle up control. If you leave the line open, it'll constantly be upping your idle. I just filled the end of the fittings with silicone and let it cure fully before installing the lines back on. And there is no vacuum advance on a 22RE distributor.
