Newbie hello and a 348 mystery wire question

Hi Folks, I have recently purchased a 94 348 Spider. I am really enjoying the car and am getting to know it. I have been lurking here for a while while I learn my way around the car.

I have been working around the dash and pulled the passenger side air vent right under the base of the A pillar and have found a dangling wire. It is a thin black single wire that comes out of a gap along the top edge of the firewall and hangs down about 4 inches. It has a white connector on the end that contains a female spade connector that is about 1/8 - 3/16 inches wide. A picture of the mystery wire is attached.

I initially assumed it was the factory wire powering the tweeter (the tweeter seems to be wired aftermarket) but the wiring diagram colour code suggest this is not the case. Does anyone have any idea what this wire is for and what/where it plugs in?

Thanks for your help.

PS - I am located in Calgary Alberta and am a bit of a car nut. I have a 63 Jaguar E Type Coupe and a 75 Triumph TR6 (Supercharged) that shares the garage with the 348.

Cheers

Thanks for all of the help and suggestions however the Antenna Amplifier already has a black wire connected to it and I don't see any other location where the mystery wire might connect to it.

One thing I did notice when I took the car out yesterday is that I have lost my right turn signals....I have not had a chance to look for burnt out bulbs but this seems very coincidental. is it possible that this wire is part of the turn signal circuit.

I also wondered if it was part of the glove box light circuit but the wire is not long enough to reach those components.

Soooo....any other thoughts?

And Pap, thanks for the congratulations. Oddly I don't have many pictures, I have been too busy having fun driving. Attached are a couple of photos I took when I picked up the car from storage. I have also thrown in a picture of the Jag...just for some variety.

Cheers

Gents, thanks for the E Type kudos...a slightly amusing story.

I bought the car from a guy that lived on the west coast of Canada in late November about 8 years ago. After concluding negotiations over the phone based on emailed photo's, I flew out with my tool kit for a final inspection and to close the deal. The PO picked me up on a glorious morning (you have to appreciate the difference between late November in the Prairies (desiccated brown landscape - uck) and the area just east of Vancouver (lush rain forest - sigh)) with the Jag freshly washed and absolutely glistening. As he pulled up I knew I was buying the car, but went though a thorough vetting. I then agreed to close the deal, paid him and jumped in the car at about 2pm to drive home. As I pulled away, I realized that I had not actually driven the car yet.

The drive home is about a 10 hour trip through the Rockies including the high mountain passes of the Coquilhalla highway that gets a huge snow pack (if you watch Highway to Hell on Discovery, you will know what I mean)...remember this is late November so it is dark by 4pm. It also happened to be Grey Cup Sunday...Canada's equivalent of the Super Bowl. Bottom line I was in an unfamiliar 45 year old car and there was hardly anyone on the road...but... there was a high pressure system over western Canada so no snow.

I tested the car on the long climbs up through the passes and it pulled like a train...quite turbine like. The only vehicle i saw on the Coquilhalla was a 1 ton diesel monster truck that initially blew by me in a cloud of black smoke while I looked out the side of the car at the hubs of his wheels. The cowboy in the passenger seat looked down at me with a bit of a snear. I gave him about a half mile then stepped on it. He was a spec in the rear view mirror a couple of minutes late. Them cowboys don't like that kind of treatment.

It was a great drive home through the Rockies with a clear night and the stars out in full force and a great memory.

Now...back to F car business....attached is a picture that shows more detail of the black mystery wire. It comes out of the fire wall at the same location as the another black wire that is connected to the antenna amplifier. The mystery wire slightly obscures the view of the other black wire connection to the amplifier in the photo.
so....any thoughts as to where the mystery wire connects?

And as a reminder, my right turn signals have stopped working ...coincidental with the removal of the vent passenger side air vent which is what caused me to see the dangling mystery wire disconnected so I wonder if the removal of the vent is what caused the disconnection of the mystery wire and if the mystery wire is part of the turn signal circuit. Note I have checked all of the turn signal bulbs and they are good.

Any thoughts greatly appreciated....'cause the next step is to start pulling the dash apart.....which I really don't want to do.

Thanks Mike....I will go back to sleuthing andcareful review of h wiring diagrams.

Hmmmm...now that is a good question given the proximity of the wires. I dont know and dont have records form prior owners. The windshield looks perfect which is a bit unusual around here as gravel is used here during slippery conditions....so most windshields have some "bullet holes" in them from flying gravel.

I will just focus on getting the turn signal working and not fuss the mystery wire too much.

Cheers

Now that is a very excellent question.....the amber lights on all four corners work. More thinking for the wiring diagram....perhaps the turn indicator switch?
