Norb...in the 88 sedan bridge, it's under the floor immed as you step past the sliding door into the v-berth area. Access may be covered by a piece of carpet (abut 2' x 2'). Once you lift the carpet, you'll readily see the sliding wood floor panels over the sump. BTW, if you have air conditioning, the condensate should be routed to drain into the shower sump - many are and it works well in this arrangement. Make sure you keep the sump pump switch on while you are running the AC.
