What are these wires??

Hello
i have a mk 1 Golf GTI cabriolet 1983
I have 2 x white with yellow tracers wires coming from where the radio fits that I haven’t got a clue what they are for??
on 1 of the wires it has continuity to a 6 pin block connector on the back of the dash insert

any ideas?

So 1 wire runs from the dash pod to the radio area - what should it connect to at the radio end?
the other wire runs from radio area and the other end is at the fuse box in nsf footwell with a plastic connector on but it’s not plugged into anything??

I suspect, that it is for constant power for the radio presets, but I don't have the Radio guides for the 83.  

On my 81 tin top the Radio had power live full time, and I changed it over to switched, so I couldn't drain the battery.

Originally, they would have been joined together in the radio connector. It comes from a speed sensor (probably a hall sensor) in the speedometer . It then goes to the radio and continues to the fuse box. I was told but never seen one working that it alters the volume of your radio depending on speed. Just tape them up unless you're planning to use an original radio.

Perfect, thank you for your help.......again!
