2006 G35 key intermittently beeping in ignition

[vq35.jaay]

Hi all! My name is Jordin, 2 months of ownership give or take. 2006 G35 sedan, not sure what specific model, but I'm having some weird issues. The beeping the car does when the key is in the ignition cuts in and out like there's a short or something in the area. the pedal sensor is having constant voltage correlation but before I started doing these deep repairs and inspections it only pulled low input codes then voltage correlation after wiring repairs. I still have a LONG ways to learning and going about this car, but I'm starting a job soon and would love to have your guys' help as this seems to be the MOST active forum for these cars other than Reddit. id like to know about all of these connectors around the steering area and under, and what the F this thick blue wire is that's spliced into my throttle body connector. thanks!!
