Re: serpentine setups..info please
The first pics are your AIR injection pipes into the exhaust manifolds. The rest of the pics are the one way check valves to keep from putting exhaust into the smog pump. If you are getting rid of the smog pump, you can pull that off. It will not set a check engine light. You can unplug the electrical connection to the switch on the check valves and just folt it cack into the harness to get it out of the way. The last picture is your brake pressure switch (I think). If not that, it goes to a high pressure switch for the Power steering. Either way, leave that one.
