I got a cheapy one first ($60 bucks) knowing that was wrong. It ran worse with that than it did with the old no name one thats on it currently. Im a BMW fanatic and its the same for those, Bosch only. So I searched what brand is oem for these and came up with bosch. I orded a Bosch one and it came, but its wrong. Mine is a 3 wire. Bosch seems to be 5 or 6 wires. What am I missing? Thanks in advance peeps!
