Glow plug relay in slot 2 ?

Howdy folks. I fitted an aaz engine in my cabby. Can I use slot 2 in the fuse box which would have had the fuel pump relay?If so  does anybody know the part number? Thanks 

It is probably better to use a fuse panel add on at the top. Then you can wire it correctly as you want it.

Thanks Brian , I was looking at that yesterday I'm a grease monkey electrics make me dizzy . I'll  look at it again and make a list of what I need . Looking for easy options as always with wiring . My Haynes diesel manual showed slot 2 for glow plug. Thought it be simple as that. Thanks for reply mate
