Here's a scan of the electrical page from the manual. I see the "M" on the switch

GTS, then, like the earlier Hondas. (GX-630, 660, & 690 are GTR if you upgrade)
What I did (because the generic relay with socket was 'hanging around') was to tie the Low Oil Shutdown and coil wires to the NC term and ground the 'commons'.
When the relay is energized they are 'open'. Either LOS or de-energizing the solenoid grounds the coils and shuts 'er down. Be sure to tie the two together after the relay and not between relay & ign terminal so LOS will function normally.
If I had to pay for the relay I would have replaced the switch instead, pro'ly cheaper but surely simpler. Easier to find this type switch on the rack than on their website, but Advance Auto is where I see switches with 'M'. tog
