also I do not believe the wiring chart at the top is correct. No way pins 14 and 15 are empty.. all late E30s have a pin 14 and 15 (VSS and unloader relay). same for pins 8 and 9 - unless your 318is doesn't have a tachometer or an econometer.
I'd be willing to bet pin 20 is actually red, but the wire cover has just turned brown due to age - because brown is typically only for grounds, and pin 20 is definitely not a ground.
