Missing module???

[bigcat01]

I am new to 928 ownership. Car is 1984 928s. Working on rear hatch automatic opener. Passenger side knob not working so I opened up passenger side tray to look around. Well, I found nine wires not attached to anything. Is there a missing module that these wires need to be connected to? Thanks for any help.

I think the 02 counter goes in that spot.....not for sure, but methinks.....

Yes, O2 counter as mentioned and a Blaupunkt amp for the stereo.

What kind of passenger side knob do you have?

The knob is round, has a picture of car with trunk popped open. It was not plugged in either. Car now has ken wood stereo so I guess those wires don't need to be hooked up. Thanks for the help. Just seems po didn't want to fix all the little things. I'm slowly going through car fixing those things and wanted to know if I needed to add anything to the list

Factory amp left side of the noise filter ( transformer) o2 counter to the right side
