Default Q on fog lights mod: how to cut power first?

I'm thinking about the fogs w/parking lights mod, but I noticed that the light switch is powered even when the car is off and no key in the ignition. For those of you that did this mod, did you pull a fuse to kill power to the switch prior to operating on it? If so, which fuse(s) did you pull?

Another question: one poster in the referenced thread said that you <b>don't</b> need to VAG the car at all to make this mod work, you'll just have the amber lights on with the fogs in the parking light setting. Can anyone confirm?<ul><li><a href="https://forums.audiworld.com/s4b6/msgs/333541.phtml">https://forums.audiworld.com/s4b6/msgs/333541.phtml</a</li></ul>

Default You are correct

If you don't VAG the car after doing the above mod, you can run the amber parking lights and dim city lights with the fogs only - no low beams. If you VAG the car, you can run the dim city lights and fogs only - no low beams.

Default Good info, thanks - what about the power?

Can anyone comment on the safest practical setup for working with this wiring? I think it's hot even when the ignition is off; is there a fuse I can pull?

For those of you that made the mod, what did you do to prep for the wiring work?

I know that disconnecting the battery is probably the safest, but I'm guessing there are some electronics that have to be reset if this happens.

Default I pulled the switch

I didn't disconnect the battery, although that's probably good practice. It was pretty tight to get in there and I had to pull the switch from the plug to have room to work.

Default Just finished - it works!

I wanted to be super-clean on this and pull the #2 wire out of the connector and use a new wire to patch. But, it is darn tight in that space and I couldn't get the wire free, so I ended up just cutting it and stuffing a new section of wire between #1 and #2 on the back of the connector. It works, so I'm calling it good.
