Default Headlight Relay replacement

While taking stuff off the car to start installing my turbo bits, I noticed one of the wires that goes into the headlight relay socket became disconnected because of a corroded relay socket. Figured I need to splice in a new socket/relay and given the stock relays aren't too available locally I'd just as well go with a more common relay.

Of course, it'd help if I knew anything about how/what to source...

From the schematics it looks like a 40A capacity SPST relay with a 4 pin socket would work?

Because both main fan relay and headlight relay look to be the same I thought I'd replace both at the same time.

Will this work:

Yes.

Nothing special about the headlight relay in a Miata. SPST, 12v coil. Ditto all of the relays in the engine cooling / aircon system.
