My 2008 XJ8 started throwing error codes and messages. I narrowed it down to 1 connection on the Front Electronic Module. The connection is known as CR9. All I can see different when it is unplugged is the windows don’t work. I don’t know what other things this connection is connected to.🤦‍♂️

Anyone have any ideas as to what I can do? I feel lost right now.🤷🏼‍♂️

4 harnesses go on the bottom. The outlined part is the 3rd one from the front of the car.
