I can't really say for sure what year it's from. I am trying to install the outside temp diplay in my 83 300D. To my knowledge, there are only 2 types of connectors for the temp display. 1) A 4 pin square connector or 2) a straight (pins next to each other in a line) 5 pin connector. I need the 5 pin version for the temp display I have. I think the 5 pin may be the later of the 2 types, as the 5 pin is from the speed sensor to keep from adding temp while driving. I can try to reasearch further if necessary. How many cars with temp display do you have?

Looks like 4 pin before 9/87 and 5 pin after
