Fuel injector electri bar

What is your question?

I just replace the starter in my 3 to 5 2001 BMW and after replacing everything I've come to a problem the fuel injector bar that has the six plugs that snap into the fuel injector there's also three other electrical cords that come off of it one in the front towards the front of the car that plugs into something there one in the middle that actually connects to the air intake and then the third one is in the back by the firewall but I don't know where it plugs into and I'm having a hard time because my car still broke down can I get a diagram of the actual places where they plug in because I'm stuck it's been 14 days and I can't find the answers

How long has your 2001 BMW 325i had this problem?

Since i replaced starter
