ok I got a check engine light on, on my 01 s2k and it's because of my air pump that goes to the cat. I have one vacuum hose that goes from the pump that is not connected... maybe a noob question but where do I connect it? Anyone know where i can find instuctions on how the pump relay is connected? Thanks

 

One hose should go to the intake arm, between air filter and throttle body.
The other one goes to the air valve that sits on the side of the intake manifold right next to the firewall.
