Wow that’s an early radio looks like my e24. So the yellow and blue should have a home in the radio you pictured. They are your speakers under your orange fuse where it says L \ R. White wire is power antenna/ amp power. From memory I can’t remember e34 early cars but white purple should be switched power. red green should be constant or “memory” . and brown ground (these are e30 colors so they may vary, use a test light to find properly).... now from memory again your top plug of radio left to right is ground (brown), power antenna (white), the last two should be your powers. You Might need to make some connections useing insulated spades if the connectors don’t match
oh shoot I’m sorry are you installing the after market or oem?
