What is this connector/circuit?

Looking at the drawing it is confusing though. Generally pink is hot +12 from the lighter feed, yellow is door switch ground and yellow/ black trace goes to the ignition lamp and also headlight buzzer if equipped. Yellow or yellow/black trace should be to the map lamp switch as well as it just passes the door ground or when the switch is flipped switches to ground via the case of the switch. That drawing is subject as I believe it is in errror. Anyway what is missing and plugs in to the connector in your pic is the time delay relay as shown.
