remove the hose from the PCV and shove the end into the bottle, it'll suck the Seafoam into the the intake. Try to keep it from stalling out if you can, shut it down and let it soak for about 10 minutes after the bottle is empty. When you start it up, tell neighbors you are getting rid of all flying insects within a 3 mile radius, and be on the lookout for the volunteer fire company.

I unhook the vacuum line to the brake booster and slowly pour it in.

On my '96 I just use one of the unused vacuum inlets in the center of the intake manifold. Attaach a long vacuum line to it, sit in the driver's seat, put the hose in the seafoam can and let it suck it into the intake. That way I can feather the gas pedal to keep it running while it draws the seafoam in. On the '97 LSC I use one of the two vacuum hoses that go into the intake next to the throttle body. It works pretty well.
