Yesterday I took out the speedo and took advantage to have a look in the big hole.
I found four small red wires with connectors.
Two of the wires are connected together.

I allready found out that about all the possible wiring could be in the car, even for stuff that isn't mounted.

Any idea about the use of these wires ?

(sorry, no digital camera around)

What colors? They may be for the fog lights.

I think they were red with white stripe.

I'll be able to tell you tomorrow (euro)evening.
I was just closing down ...

Red with a white stripe is power to the gages and insturment lights.

The red + white stripe is energized when the key is on, and provides power to the gauges. (NOT the gauge lights, the workings of the gauge.)
