If the body is round on the relay pictured, and it looks like it is, you need a 000 542 9719 which operates the cold start valve.

This relay is used on several different Mercedes for several different things, but the cold start valve seems to be what it is used for on your 1972 4.5.

These are usually about $35 each.
