The same way you take it off! But in a reverse order.
Into the power steering reservoir under the hood.
The power steering stays where it is at. There is only 1 bracket that won't hook up and that is the one that bolts to the factory exhaust manifold. You will have to modify that bracket are make a bracket that will hold the power steering pump and keep it from moving.
Use the Power Steering bracket for a D15b7.. Yes some of the D15b7 civic's came with power steering!! I think all D15 Power steering brackets will work. D15 brackets will not work!!
The power steering fluid reservoir is up on the passenger side wheel well in the engine bay. Looks like a short fat silver coke can with hoses coming out of it. On a side note, the 300zx twin turbo uses ATF (automatic transmission fluid) not power steering fluid. usually a green casing with black top. the following link is NOT a 300zx, but the reservoir is about the same. http://www.sillbeer.com/images/engine/power-steering-reservoir.jpg
Remove air filter assembly. Loosen Belt, place pan under steering box, disconnect high pressure and return hoses. Remove bracket to engine bolts, remove pivot bolt, remove bracket and pump as one whole unit. Then reverse the process to install.
Automatic Transmission fluid
On a 97 with the supercharged 3.8L the power steering pump is not mounted on the same bracket as the alternator. The Alternator bracket includes the belt tension arm and has two water lines running through it but the power steering pump is mounted below it on the back of the engine. Why are you pulling the pump?
At the front left side of the engine, if you are looking under the hood.
its on the passenger side silver with a black cap.

Put it back on and tighten the bracket.
Secure the power steering pump with the retaining bolts. Attach the power steering hose to the power steering pump. Put the belt on to the power steering pump. Fill the power steering system with fluid.
