I removed the air filter and the box it sits in (the housing) and saw this wiring harness that had very brittle plastic. I bet its only a matter of time until the the connection fails or the wires start shorting out. Can you tell what these wires (wiring harness) is for??
Its from a 2004 s80 2.9l

 

The trans. The wires will be fine. You can buy looming at a parts store if you want.
