Unknown Wire

Post by KLiff » 28th October 2020 - 5:07pm

Can anyone shed some light on an issue for me please: I noticed a wire hanging down underneath my car, by the front axle so took my 1968 1600 L squareback to my local garage. After some fiddling he managed to trace the wire up into the front boot; it came through just by the windscreen fluid reservoir and went along the bulkhead under the boot card to a black cuboid box coupling which had two square plate connector pins. The wire then continued left and disappeared through to the dashboard (in the top left corner of the boot, uk drivers side). The mechanic tested the wire under the car and it was not live.

I had the car restored about 10 years ago and a new wiring loom was installed. This cable is original (according to my mechanic). Does anyone know what is is for - where it leads back to and what it was attached to under the car originally?

What colour is the wire? All VW original wiring is colour-coded which should make it easier to identify.

Does the Horn still work? -That's the only wire You'd expect in that area- Horn would normally be Black/yellow, but maybe the new loom used a different colour?

Black and red is Brake lights on a factory wiring loom. As has been said the only wires that should be in that should be in that area are for the horn. 1 Black and yelow, the other brown.

Could be dual circuit brakes with two switches? Or a switch removed and that's resulted in redundant wires wandering off?

Everything's working. I'm going to have to assume that it is part of the original wiring-loom, somehow and for some reason misplaced.

Thanks for you comments,

Kevin

Dual circuit brakes had two brake light switches, so its entirely possible one is disconnected and the brakes lights will still work.
