Battery Disconnect Switch and Relay Question

[landy]

I was planning on replacing the main battery disconnect switch , but the previous owner had installed a non-original combination switch and relay.

After looking at the wiring schematics, I see that the original setup had a battery disconnect switch and a separate relay. Where was the original relay mounted, next to the switch, in the engine compartment, or?? I assume the relay is available from the usual sources? Thanks.
