E12 flasher & turn signals not working.
 

New to this forum so forgive me if I'm posting in wrong forum. Found old BMW forum for 2002, Bavaria, but wasn't sure if e12's belonged there as it isn't quite that old. This 5 series forum starts with e28, so this may not be right place, but e12 shares many parts with e28. Anyway, searched other sources and learned turn signal and 4-way issues are often related to 4way flasher button. Used their info to remove, disassemble, make typical repair so button will lock in but still no lights. Looking for wiring diagram for 4way button switch so I can check its operation. Appreciate any help.
