I was wondering what this part is and if there is a replacement. It SEEMS to run down to a hole behind the passenger fender lining.
The car still isn't starting and I have not tested the starter yet because I haven't had the time.
Plus there was a rat living in my engine bay... the trap didn't go off but I think it's gone now. It chewed up some parts of the hood which I am very sad about.

Believe that is for the 02 sensors

i'm not sure , but i think the O2 wiring comes out of the central loom above the manifolds.
If the broken loom you show has many wires in it ? .... it can be the wiring of the option auxilary heater ( Webasto ) ... i removed it and indeed also cut that loom. That one is sure going down a hole in the passenger side fire wall.

I just checked on my 850, the O2 wiring is just below the connector in question. What you are looking at is part of the engine management system (coming out of the E-Box. Very likely that these are fuel pump wires. Do you have a wiring diagram book handy? I don’t have one at the moment, so couldn’t say with 100% certainty, but those wires go down and towards the back of the car.

Okay thanks everyone and no I do not have a wiring diagram.
