My quest to find a replacement ovp relay from a junkyard is coming up real short. I can't seem to find the same one that is in my car. My 87 300e has a relay that has 6 pins, one of which is just plastic to guide. Every other car I have come across has either 7 or 9 pins with 2 fuses. What is the story? Was there an update to my ovp relay/wiring that was never completed?
