There are symbols next to each lug. Typically square, half-circle and triangle with the 4th lug having no symbol. Those will match up with the label on the can and possibly the schematic.

This recapping article has links to several articles with photos that illustrate different ways to replace electrolytics that are in cans:

Some people just disconnect the old can connections and install the new electrolytics on a terminal strip that they fasten nearby. You can also cut off the old can and drill holes in the base and install the new cap leads through those holes (soldering them to the original terminals). Another way is to cut off the can, empty it, and "restuff" the can with your new electrolytics.

All of those methods are shown in the articles, along with photos and explanations of what is being done.
