Yup. The circuit loading will be the same, as the relay takes near zero
current.

(b) can anyone recommend a suitable relay
(with a web link if possible)

I think if you order it from a shop you'll avoid postage and minimum

This has 1/4" spade connectors so you could use the crimp on types, or
solder if you have a suitable iron.

I'd fit it inside an adaptable box with knockouts which you'll get from
any wholesaler or:-
