Need help hooking up Marantz 7 and 8b

just got my father's marantz set back from being refurbished. the inputs are not color coded and i'm not sure how to match them with my speaker terminals. How does one tell? any advice on hooking these two up?
I am afraid I don't understand your question. I have an 8B and an 8 and my inputs are marked L and R. By the ay I had my 8 refurbished and the dealer returned it with the fuse holder missing and he just shrugs it off. Any idea where I can locate a fuse holder? Tfactory was no help. I thot some web sites offer help with missing parts.
