What terminals does the old-style relay have?

The diagram shows four terminals: a large "pos." (positive) post on the left, a large "neg." (negative) post on the right, and two small terminals on the bottom labeled "s." and "i.".

Where are the S and I terminals located on the old relay?

According to the diagram, the "s." and "i." terminals are the two small terminals on the bottom of the relay, with "s." on the left and "i." on the right.

Which side is the positive post on this relay?

The diagram labels the left-side large post as "pos." (positive) and the right-side large post as "neg." (negative).

This is a simple hand-drawn schematic (likely created in a basic paint program) showing an older-style round-can automotive relay, typically the fender-mounted starter relay/solenoid style. The relay is depicted as an oval labeled "relay" with four terminals: a large post on the left labeled "pos." (positive), a large post on the right labeled "neg." (negative), and two smaller terminals on the bottom labeled "s." and "i.". The drawing serves as a terminal identification guide for wiring the old-style relay, presumably to compare against a companion diagram in the same album ("New Relay.JPG") when replacing or converting between relay types. A reader can learn the terminal layout of this relay: the two large side posts carry positive and negative (battery/load) connections, while the two small bottom terminals are the "S" (start/signal) and "I" (ignition) terminals. The document contains no part numbers, year, model, wire colors, or additional text beyond the five labels.
