Help on identifying chewed wire on bank2

[jeff993]

Hi All,
I got a Boxster S 2000 last year.
Having not been used for some time, i've caught up on the maintenance and checked on Durametric codes.
A knock sensor connected to ground led me to find out some rodent damage on top of bank2: the knock sensor wire was chewed. I fixed it and this is issue came away.

I've also found an other grey wire (see below) chewed, but cannot figure out where it is going to.
Any idea ?

Aside from this, the car is running fine. I get P1130 once in a while (no CEL), and clean the throttle body. I replaced the AOS. Can it be linked to the evap line ?

Thanks,
Jeff
