63 under dash wire
I was working on a 63 coupe and noticed a black wire with a green tracer and female connector hanging by the driver side kick panel, right by the headlight circuit breaker. I checked the wiring diagrams in the 63 corvette shop manual and don't see a black wire with green tracers shown. Anyone know what this wire is for ? An option maybe? The vette runs fine and everything works, the radio is aftermarket but this wire is nowhere near the radio. Thanks in advance for any info.

Brian,
Does the 63 have a buzzer tach?
Could it be the wire to the door switch for the interior lights when the door was opened?
Is it a PW car?

Re: 63 under dash wire
Hi Joe, since the interior lights work and the black with green tracer wire has a female connector on it I'll rule that out. Not an Power window car, but the buzzer tach is something to explore. Thanks for your expert opinion Joe , sincerely BrianComment

Re: 63 under dash wire
Well, after looking at the original wiring harness blueprint for a '63 Corvette, I don't find any listing for a black wire with a green stripe on the IP wiring blueprint. Might be useful to find out where it comes from, but It is not likely a factory piece.Bill Clupper #618Comment

Re: 63 under dash wire
Bill and Brian,
Don't think the buzzer tach was included in the wiring diagram as it was added to some buzzer tachs and not to others. The buzzer had a wire? for the power source from the fuse block, another from the tach to supply ground.
Could be that power source wire????

Re: 63 under dash wire
Joe,
You are correct. It is not part of the speed warning wiring. Those are their own little harness consisting of red and or pinkish, and blue wires that would be nowhere close to that location.
And yes, pinkish is an official color in my world.
Brian, can you post a picture so we can actually see the location and connector for ourselves. It just might trigger a memory.
Best of luck.

Re: 63 under dash wire
Brian,
I have the interior out of my 63 right now. I will dig up the old harness and see if that wire is even there on mine.
Is your car an early built car, or was it actually built in 63?
Mine is a very early built car built the first few days of November of 62.
CORRECTION: I got the picture from a thread about "1963 headlight circuit breaker"

Re: 63 under dash wire
Hi Monte, the 63 coupe is not my car it's my Uncle's car. I have 66 convertible I'm restoring right now, and I noticed the wire hanging the other day when I did some work on it for him (adjusting the turnsignal switch cable). I never really looked at his VIN to see when his was built (I'll check next time I see the car) The car is Sebring Silver with Dark Blue interior, and thanks again for posting the picture.Comment

Re: 63 under dash wire
Hi Richard, the wire as seen in the photo Monte posted is too far away for the speaker I think. And its a single wire with a female factory connector, I figure it's got to be for an option since it's not listed in the 63 Shop manual wiring diagram.Comment

Re: 63 under dash wire
Does anybody know what the back up light option lead looks like.
Brian, have you tested the wire to see if it is hot, or if it is grounded?
Also, I agree, there is no chance it is speaker related.

Re: 63 under dash wire
Yes the speaker wire only goes between the radio and the speaker, so if that's in your dash harness, it's not the radio. But radio came to mind based on the color.
Look to see where it goes into the harness, and if so follow it forward to the left of the wiper motor. If it looks like it goes through the big grommet in the firewall, check in the engine bay for a telltale.
The backup lights get connected to a plug in the engine harness next to the wiper motor. But IIRC the wires get buried in that harness and pass through the grommet mentioned above. Inside, they'd be wrapped in the harness, but come out through the "Body" connector going back to the tail lights, etc in the Rear harness. The body connector rear harness wiring goes behind the driver side kickpanel.
Like this switch, only this one has a Powerglide automatic neutral safety also. The Violet is the Neutral Safety, the Green is the Backup Light. It plugs into the engine bay plugs next to(Green) and above(Violet) the wiper motor.

However, in looking through my old '63 photos, I noticed this one......

It's the Park Brake Light switch plug and harness. It's a separate Black wire and a Green wire, but married side by side into a pair. If your green wire was separated from the black wire, it could leave a "trace" of the opposite color on the each one.
Maybe?
Here are a few more pics of the '63 underdash for reference.....

Re: 63 under dash wire
Brian,
If it's the green wire in Monte's picture then it's the horn wire. This wire runs down the steering column and plugs into (I think) a black and gets clipped to the vent cable. Replacement bearings (NOS) have a green colored wire instead of the original black color that runs down the column from the upper bearing/horn contact.Comment
