Love Controls 16b for Dummies

A friend just gave me a love controller that they had no use for.  The only problem is I’m a little illiterate when it comes to wiring diagrams (and I think they are as well, hence the free controller).  Can anyone out there help with where to put put what wire?  To me it looks like the black wire goes to post 4 and the white to post 5 and that’s about as far as I get.

I googled ‘Love Controls 16b’ and the manual I pulled up showed #4 and #5 being the power in.
