Green relay for K jetronic engines (B21E B23E B200E and B230E)
White relay is for LH injection so B23F B200F B230F (inc FT, FK and GT engines)
The white relay is available in both original and aftermarket
The green relay is now not available original. The aftermarket ones are not great. Best to have one fitted and one as a spare in the glovebox
