1970 European Wiring Harness, Fog Light Switch? Options

[proto31]

I placed this post in the Garage as well, but maybe it's more appropriate here. So, I'm installing my wiring harness (4 cylinder), it is a european harness. I'm making this assumption based on one main observation (although there are others that seem to support it). The observation- this is a new harness (unfortunately I do not have the part number... sad.gif ), there are NO wires going to what would be the side marker lights. Nothing (absolutely certain) has been cut, I can trace all wires and there never were any side marker light wires.

So, my problem is this, there seems to be no wiring coming out of the harness in the passenger compartment area for a fog light switch, there are, however, wires for fog lights up near the front bumper area where they should be. The main wire (white with a yellow stripe) enters the passenger compartment area and goes to a relay, which then jumps directly to the combination relay, from there there are no wires that would normally go to a switch.

I know that there was some different functionality with the Euro fog light operation, but what exactly was the difference? Do the fog lights turn on any time the headlights are on, meaning no need for a fog light switch? Do I need a special head light switch?

Any help would be greatly appreciated!! biggrin.gif

He's not talking about fog lights, he's talking about the driving lights...
( My Euro 6 had them too... )

Well i'll be damned ...

German cars, especially of that period didn't have "driving lights" they way American cars have them.

The only thing i can think of is that because the headlights were otherwise hidden, Porsche added a additional driving light option to replace the fog-lights???

If you are thinking about 'driving light' in the context of 'running light' - that's not it.

These are (very) high-intensity clear-lens supplemental pencil-beam headlights.

This is a nice rationalization, but I expect the practical reason is that all the stalk, relay, and headlight function was 911 bits on the /6's, and they just didn't change anything from the way the 911's worked.

I would love to see if a little-known 911 headlight mode made it into Euro /6's -- when the parking (city) lights are on (first detent on the headlight switch, illuminates a green dot in the cluster) the 'flash-to-pass' illuminates the _low beams_. I thought this was quite clever and I've never seen it documented - I stumbled onto it one night...

Hey Rich,
Here's the pics you are asking for of the little green dash light.
Parking lights on, green dasah light is on.
