Wiring harness - what are these?
In the process of replacing my brake booster, I found that the (apparently) original wiring harness was modified at some point.
I found two wires that were simply cut off in the harness. One is a black wire with an orange stripe that seems to never have power or ground connection. The green wire is hot whenever the ignition is on. I am not very good at reading wiring diagrams, but I can't find either of these wires.
I am attaching a picture of what I am seeing. Both of these are coming out of the bulkhead connector behind the fuse box. On the left of the picture, you can see the brake booster. The thicker purple wire at the top goes to the starter solenoid.
Anyone know what these wires were originally for? Thanks.

Hi Joe - thanks for the reply!
I am trying to figure out where you see this in the CSM? I have the 1971 Oldsmobile Service Manual, but a lot of the wiring diagrams are not well reproduced, like the attachment there.
I also looked in the wiring diagram posted in the electrical forum here:

That diagram is much, much clearer, but I still can't figure out where you are looking to see those two wires I was talking about.
If you don't mind "teaching a man to fish" could you tell me where to look?
Thanks!

Throw that piece of crap away and get a real one. There are at least a half dozen original 1971 CSMs on ebay at this moment, with prices starting at $10.
