The 99 relay comes is several sizes with different part numbers. "99" is clearly marked on top so they are easy to identify. They all function the same. All versions I've found are based on the ST Microelectronics IC number DD920402.

They can be hard to find because they are plug and play in some Volvo and BMW cars.

If you solder it might be a good idea to replace the few electrolytics on the board.

If this is a superseded number I don`t know for sure, could be a UK or lotus thing.
