LED Headlights: Turning on the fogs turns on the high beams, too!, New behavior, fogs worked normally until LED headlights installed. Options

[orthobiz]

I love my brand new GE Nighthawks. There is no way I could go back to regular headlights. I had a set of sealed beam Hellas.

Last night I turned on the fog lights for the first time and the high beams came on. When I looked at the front of the car, all three were on: the regular lights, high beams AND the fog lights.

Any fix for this? I would like to have the fog lights and the low beams on at the same time without the high beams.

Edit: up until I installed the LED headlights, turning on the fog lights did NOT turn on the high beams. And turning on the high beams turned OFF the fog lights. In other words, normal behavior.

Thanks,

Paul

well now i'm confused and i've read this over and over.

which is correct?

A: the blue/wht line from the HIGH/LOW relay gets grounded
B: the blue/wht line from the FOG LIGHT relay gets grounded

This would be the same wire except it appears it could be physically connected at a different point.

A: On my '71 the white/blue wire was physically connected to the high beam spade connector at the high/low relay.

B: In the car pictured by Chi-Town via Bruce, this white/blue wire is shown connected to the high beam fuse on the fuse panel. Maybe a later year car?

In either case, this is the same wire and should be removed from its current position (either cut at the connector if in A: or pulled from the fuse if in B: )

Make a pigtail of about 1 foot of wire with a ring connector on one side, and on the other side either:

A: Crimp the white/blue wire cut from the high/low beam connector.
B: Crimp a male spade on and connect to the white/blue wire pulled from the fuse. Put shrink-wrap on the spade connection as to not touch any of the 12V power in the fuse panel. I would not recommend taping this off as the tape may come off and short to any of the 12V power.

The ring connector side of the wire is then connected to a local chassis point.

Edit:
Looking closer at the 70-71 and 72-73 diagrams I see a difference on the fog light relay ground. Only the 72-73 shows the blue - white wire to the #1 fuse.
I need to get all year diagrams.

Wire diagrams show the blue-white wire is connected to the #1 use spade fot 1970-1973 cars.
I have not checked diagrams for 74-76 cars.
Chi-town shows a 73 harness.
My bet is that all years have the wire in the same location.
