Default What does this brittle cable go to?

Anyone know what this is for? I currently have a P0411, could this be the culprit?. I'm not sure where this cable goes. Any guides on getting it fixed? I have another similar cable next to it too you can't see in the picture.

looks like the sheathing on your vacuum line. Replace it if the rubber hose inside is brittle and cracking.

Any guides on this particular one? I can't really see where it goes or what to take off to get to it

Not sure what engine you have. I can't tell also from this photo where it is located in your engine bay. The only reason I say vacuum line is because I just replaced all of the ones on my son's car and they looked identical to yours. I only have minor experience with the 3.0 liter engine. If that's what you have, there is a guide out there floating around that shows photos and gives step by step procedures for what to do and what you will need.

Not sure exactly where that is or which line you are talking about; is that the intake hose on the right forward side of the engine? And then which line: the large one, the vacuum line in the middle, or the braided one at the bottom.

Also, below is the troubleshooting guide for P0411:

16795/P0411/001041 - Secondary Air Injection System: Incorrect Flow Detected

Possible Symptoms
## Malfunction Indicator Light (MIL) ON

Possible Causes
## Fuel Pump Relay (J17) faulty
## Hoses/Pipes to/between Components faulty/clogged
## Secondary Air Injection Pump (V101) faulty
## Secondary Air Injection Pump Relay (J299) faulty
## Secondary Air Injection Solenoid Valve (N112) faulty

Possible Solutions
## Check Fuel Pump Relay (J17)
## Check Hoses/Pipes to/between Components ## Check Secondary Air Injection Hoses/Pipes for Carbonization

## Check Secondary Air Injection Pump (V101)
## Check Secondary Air Injection Pump Relay (J299)
## Check Secondary Air Injection Solenoid Valve (N112)

The braided on the bottom. I'm not sure what guide to use to get to it and replace the hose.

That would be the hose connecting your N249 boost pressure control valve to your diverter valve. It has nothing to do with a P0411.
