Another "where does this wire go?" thread
 
Car is a 1977 911S Targa with 1984 3.2 motor that I bought last year to replace my wrecked 1984 (motor is from that car).

It had been hacked on and neglected by 4 previous owners, so I am working on the electrical and interior currently.

The hazard switch was jammed in the ON position, causing a battery drain, so I replaced it over the weekend with a OE Porsche part. I noticed one brown wire with a inline resistor is not connected. This should connect to the headlight switch? There is a dangling wire there as well, with a matching spade connector.

I also found this unused pair coming from the left footwell area. Appears to be red with black stripe and brown. Could not get any voltage. Any ideas on what it might be for?

There is an unused yellow wire under the dash near the radio opening (no radio currently in car). Does have 12V when ignition is ACC or ON. This is the radio power?

TIA,
Julian

The bottom picture looks to be speaker wire - perhaps running to the rear-deck speakers.

Looks like that brown wire with resistor (N6) connects to emergency flasher switch at terminal 58. the other end connects to a red and black wire via (T1f) which connects to terminal 58a instrument light potentiometer (E20), part of the head light switch.

Radio wire is Yellow.

Yellow wire = radio √
Brown wire to headlight switch √

I'm still left with the paired red/black stripe & brown wire in black plastic sleeve that goes up into the abyss around the left defroster pipe. Could be speaker wire, but I have not seen speaker wire covered with a sleeve.

When I looked on the schematic, there was a few red w/black wires so hard to tell for sure which one it is.

I will try pulling some gauges out and see if I can tell where it goes.

You were mostly correct. This paired wire turns out to be for the driver's door speaker. The passenger side wire is still there as well, but has a connector and no sheath.
I figured this out after taking the door panels off for replacement (2 large speaker holes hacked into each, and I mean hacked. It looked like it was done by a beaver on meth. Luckily the door panels were not original, so I feel better about replacing them.)

I'm using some Sony 6.5" 4 way speakers (that I already had laying around) in the doors, Poly-Planar shallow 6"x9" enclosure speakers on the rear deck, and a Blaupunkt Cupertino AM/FM/CD in the dash. Probably won't be able to even hear it while the motor is running, but it should look good.
