Fog / Driving Light Rewiring Hack, I'm having trouble figuring out which wire to ground Options

[LefthandRev]

I followed these instructions for conversion #2, which should allow me to keep the fog lamps on when high beams are on... but I can't seem to get this to work.

According to these instructions, on my car, terminal one only has one blue/white wire. My car was an 08/73 build, even though the VIN shows '74. The '74 wiring info doesn't match this car (and really, all of the features of the car are '73, such as the bumper and other minor things, so I'm treating it as a '73.)

Can anybody guide me on this? I'm a little boggled.

Thanks!

Mine is an early 72 (March).

Using an Ohm Meter and referencing my wiring diagram, I made a sketch of the Foglight schematic, switch and relay (pin ID's) to better understand (for myself) how the electrons were moving.

Not sure if this sketch will help with your late 73 build (others may chime in).

For me, the white/blue off fuse 1 was moved to ground. This allowed me to have the driving lights on with parking lights only as well as high beams.

Good luck.
