What problem(s) are you having?

There are two separate vacuum systems in your car, and there is no nipple on the brake booster line to look for (assuming it is the same as my '96). The vacuum pump on the engine supplies vacuum to the brake booster and for engine-related functions (EGR, intake flaps). There is an electric vacuum pump under the back seat, RH side, that supplies vacuum for everything else including the door/trunk locking and HVAC systems.
