The relay pin out is a common design and not Suzuki specific. I "borrowed" an unused relay from the wife's Mazda 6 when I fitted fog lights to my XL-7
. You should be able to buy one from an auto electrical store.
Something to note is only the top right green relay socket is populated with pins- the others aren't electrically connected (if you look closely at your pics.) Even that socket looks like it might not have all the required wiring to function?
