I have a ? about my fog lights
 

The fog lights on my 1974 914 only turn on when the high beams are on. I was wondering if thats how they are suposto work or if I have a wireing problem it dosnt make sense to me because if your driving in the fog you cant see anything with your high beams on. If any one knows whats going on with my lights please let me know any help would be greatly appreaciated.

Thanks,
Timmy

My 74's fogs only turn on when my lights are on. I think there is a way to make them come on when you turn on your driving lights(little orange ones).
It sounds like you may have a wiring problem.

above is a bunch of wiring diagrams.

Your fog lights should only turn on when you have the "low beams" on. The best way to correct this is to exchange the WH wire with the YW wire which feed the fuse pairs, F1-F2 with F3-F4. You can do this simply by pulling the wire connectors off the fuse block and reconnecting.

I played around with this when I was changing between foglights and driving lights (fogs are used with lowbeams and driving lights are used with highbeams, or both).

Here's a pic of the connectors & relays involved:

drl's?
 

My fog lights have been rewired so they can be turned on any time the ignition is on. I can use them with high and low beams or just the parking lights. Mostly I use them as a daytime running light to increase my visibility in poor lighting conditions such as when oncoming traffic is driving into the sun. Like the headlights without the aero drag and electrical load of all lights. Hopefully keep someone from pulling out or turning too close in front of me.:eek:

campbellcj,

that is the BEST pic of the fuse relay board! I wish all instructions came that well illustrated. But I am not sur eI understand WHAT moving the white and blue lead to the other terminal accomplishes. Can you now use your fogs anytime??

Moving the wires does TWO things....

Allows the fogs to be used without the headlights being on AND when the high beams are on. Basically converting them to driving lights. Smart driver change the lights also.....IF they are using them for driving lights....fog lights have a different beam pattern than driving lights do.

Moving the wire between the two terminals shown in the pic is to change it so the foglights can be on with the high-beams instead of the lowbeams. I did this when I put driving lamps on the car.

The pic is a 73 relay board. Not sure how similar/different other years are.

There was a change to this wiring from '74 up. In Chris's photo there are two white/blue striped wires crimped into a single terminal. One of these is power to the high beam indicator. The other provides a ground path for the fog light relay through the filaments of the high beam bulbs when they are not on. In '74 the wire for the high beam indicator was crimped into the wire on the other side of fuse #1. Only the fog light wire was in the location in the photo. On '73 and earlier cars moving both wires will cause the high beam indicator to be on with the low beams and the fog lights will work with the high beams. Determine which wire is which, run the fog light wire to ground and you can have your fog lights on any time the lights are on.

There was a question about what moving the wire actually does. The factory connects the wire so that ground to the relay coil is provided through the high beam filament. When you turn the high beam on, +12V is present, and the coil cuts out. Moving the wire provides a ground that isn't dependent on the high beams being on or off.

I went totally overboard with my system and added additional relays so that I can flash my fog lamps when the headlights are down and off by pulling on the stalk. It's been quite handy. EVENTUALLY, I will write up how I did this. For pics of my conversion see the following URL:

GOT EM FIXED
 

Thanks to all who have replyed I have fixed my problem

foglite rewire
 

a long while ago GPR had a trech section on their site with instructions on how to make the lites work independent of the headlites; it seems to be vaporized now, but maybe someone can reprint it?

914 fog/driving lites
 

oh yeah: there is a Volvo bosch ROUND halogen driving lite that mounts perfectly in the 914 location; mid '70's as i recall; go check out pick'n'pull
