i bought some e36 m3/coupe rear lights (white clear indicator) i changed them with my standerd 318 is ones and im having issues. they work but when i brake the brake lights dont work. i noticed the pin connectors on the loom have 2 blank wholes on the passenger side and 1 blank on the driver but blank 1 & 2 blank wholes on the light itself but in different places. i dont understand i was told that they are a straight no problem fit onto 318is can i get some advice or help how to get it to work . the only brake light i get is on the bottom of the back window!
