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

but you will notice that they will work with the high beams rather than the low beams like the usa cars

Huh? (IMG:style_emoticons/default/confused24.gif)

I have to dis-agree with the Dr. ...
I have never ever seen a German car where the fog lights are wired to work with the high beams. Ever.

The fog lights only work with the low beams and will shut off automatically when you switch to the high beams.

Dear Sir Andy,

I must say, that this thread about fog lights is certainly one records.
1st. about my car. It is a 914/6 #9140430841 delivered in Germany, and brought back over by an Army serviceman in the 80's.

Full blown Euro model. No BS here. I have owned the car for the last 12 years now. Stripped down to bare, and ground up resto.

The Euro cars had Driving lights on them in liew of fog lights. My car had these still on it when I bought it. I also noticed that there was no switch for the driving lights, nor was there a hole in the vinyl dash fascia as if there might have originally been one that some one had earlier removed. I quickly bought a fog light switch to make up for this missing switch only to find out that there was no loose pigtail plugs for the switch to plug in to. I spent many an hour going back and forth to my '74 2ltr USA 914 to compare the wiring behind the dash, and shortly found that no one had cut or mangled any of the original wiring in my Euro 6'r.
As it stands, the Euro 6's driving lights are wired right to the headlights. Mine come on when the High Beams are activated not low beams. They are off when the low beams are on. That makes for one bright viewing area at night. Also, on my car, the driving lights are wired for a flash-to-pass feature. They activate if I pull the dimmer switch toward me when the headlights are off, or on low beam.
I thought the same as this threads author, that some one monkeyed with the wiring. Now I feel more secure that the Euro cars were wired different, probably due to different lighting laws.
I also noticed that there also is no plug for the switch on the brake master cylinder either.

Interesting. My Swiss car #1113 has driving lights that will only come on with the high beam, and it does have a switch on the dash. I can flash them when in low beam as well.

Go figure.

If you can flash the fog-lights, someone did indeed change your wiring ...

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

Since they come on with the high beams (when enabled by the dash switch) of course they flash when on low beams - just like the high beams do...

And yes, they flash even when the headlights are down.
The high beams come on when the headlights are down too - just it's hard to see. But flash on, they do.

It's all the same relay, it just depends on if the 'enable' wire goes to the high-beam (driving) or low-beam (fog) circuit. It's on the wiring diagram...

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???

I can honestly say i have never seen this on any other German car of that vintage.

Time to whip out my PET copy and do some digging ...
