Does anyone have a B5B4 Relay they'd sell?
The green one in the engine fuse box.

Best to get one from ebay. Otherwise ring up a few local wreckers as a few different other cars use the same relay.

I've had a few ebay ones and they didn't last long at all. They're very cheaply made compared to the original imasen units. I ordered my replacements from Rosenthal in the US so they were brand new and original. If your in urgent need I'm sure any mazda dealers could overnight one in stock if they don't have them already. There are also a few vendors here who will have second hand spares but you're asking in the wrong forum mate.
If you've already pulled the relay out of the car, then pull the plastic cover off and see if you can just bend the arm so it'll close circuit again. Unless it's had terminal overheating it might be reparable.

Try Bursons etc. There will be an aftermarket version available, it's just a relay.

All NA and NB MX5's had the same relay. Last one I bought cost me $5 from a wrecker.
