If I remember right you just need to take them off your AIR tubes off your manifolds then plug those.

You take the pump off and at the back it leads to a AIR diverter box. You take that box off too and tie the wires up safely. It should have hoses to both the AIR tubes in the manifolds. There is a check valve in between the AIR holes and the hoses. Take that off and cap it off. Also, one more hose goes to the cat with a check valve in between. Cap that off too

There are 3 on your car. They are what the AIR hose plugs onto. The are black and can be screwed off. On your manifolds, you have 4 little tubes going into it. These 4 tubes join up to one large tube. This tube has a black thing onto which your AIR hose is connected.

I did it the easy and performance adding way, get a set of hooker super comp headers. This way you get more performance, better sound. And this way you don't have to plug anything off. And maybe in the future u want to get headers anyway. I also removed my smog pump, my question is where do you put the wires from it? I just zip tied them off to the side. Is this OK?
thanks

I would have got the smog legal headers. I did that just in case they start doing a visual inspection and I could run to the JY and get it and have in on in half an hour to an hour.

BTW, zip tie them so they don't get chewed up by the belts.

Yea I would have but I got the car with the headers on it and the smog pump hoses were just dangling there, so I had no use for it. thanks aklim, yea i tied them away from the belt, I tied them onto the injector wireing harness
