i have a 97 bmw 528i and i was recently replacing a head gasket. when i got it put back together i noticed that on the fuel rail their are two connectors i found the connector that goes to the middle of the fuel rail but there is a connector on the end of the fuel rail towards the front of the car, and i have no idea what plugs into it, could someone help me out and let me know if something goes there? thank you
