Find the two hoses that attach to the bottom of the throttle body. Follow them back to the engine (one attaches to the black coolant "manifold" that runs to the heater core I believe). Pull one off of the throttle body and loop it back to the port right next to it. Pull one off of the engine and loop it back to the other port and you're basically done.
Other tips:
-I took a funnel and poured water to flush the throttle body, then blew it out with my air compressor to completely dry it out.
-You can partially drain your coolant into a clean bucket for reuse. This keeps you from having to deal with leaking coolant when you disconnect the hoses. I didn't do this on my car and it made a bit of a mess. I lost probably a cup of coolant. On my friends Si we were changing his upper radiator hose to a flexible stainless one and installing the IMG at the same time so we had drained the coolant, making this even easier.
I believe there is a DIY on this. Use common sense as with any mod!
