That manual is for the USA built boats with a Westerbeke engine, loads of differences in those boats to ours built in France so I wouldnt take that as gospel!Very surprised that it's just dangling in the wiring like that ... Very poor ... but I suppose that's. French engineering for you ....... Like my damned Renault car! (Wife's choice but now mine.)
The diagram in the manual, page 109 ( link in # 14) shows the relay connected to the charge warning light terminal of the alternator which, ITYWF, is the output from the field diodes ( not the main output terminal, which would energise it as soon as the battery isolator is closed)
The relay switches the negative supply to the windlass controller.
