Can someone explain what this wire is?
Just picked this up for $4k and finally able to dig into what all I see that’s wrong. Headlights also have me in a stump. Fun project but my god I feel like they royally jacked some of the wiring.
thanks guys! I’m sure I’ll be back with more.





Directly behind the rear injector is the EGR Diagnostic Temp Switch. The wire in your fingers is supposed to be attached to that switch. The system will set Code 32 after a period of time (usually at highway cruise) with that switch not connected.
