Old BMW color codes
I've had my car apart for too long. I don't know exactly which plug goes to which sensor on the engine on my US version '83 320i. The two unknown are a BR/W, BL/Y pair, and a GN/Y, BK/Y pair. And a BK/Y wire floating on its own. And what is the relay next to the speed relay on the firewall? It has BR/W, BK/GN, and BR wires on it. I have various wiring diagrams, but they don't seem to cover these color combinations.
