Keeping fog lights on with highbeams

As the title states, is there a way to change this behavior? I can understand maybe why you would do this with halogen bulbs with the stock housings, but since I've switched to HIDs for my headlights and foglights with lower energy usage, I want to keep them both on.

It is illegal (in most states) to have fog lights and high beams on. (at least on a public highway/street)

The only possible desire for both on at the same time is 'bling'.
There is no other reason for both on.
How ever i am not saying you can't.. just you should not.

I know you can do that with the MK1s by taking out the fog relay in the engine bay and running a jumper wire. That makes it so you can turn on the fogs with just the parking lights on and so they will stay on even when you switch to high beams. Not sure if you can do it on MK2s but its worth a try. There is a page on here that shows how to do the MK1 fog light hack, the only difference is that I used a inline fuse as the jumper with the same rating fuse in it as the fog light fuse under the dash just to be safe. Good luck.

And this is the first of many "it's illegal" comments.

I know for a fact that if it didn't come stock with fog lights it's really easy, however if it came with them I'm not %100. When installing fog lights you splice a wire into a orange white wire in the steering column which turns the fogs off when high beams are turned on, if I had to guess (don't have a full wiring diagram on hand) this orange white wire has something to do with it.

I wrote a fog light install a few years back if you want to check it out, it's in the "how to archive".

As always check with local laws on this topic before going at it.

Ps mine work whith high beams, but it didn't come with them.

Wire them to an AUX Switch. Mine didn't come with fogs, so when I installed the factory ones I wired them to a toggle switch.

Thanks for the help guys. As for the legality of it, I can honestly say I don't really care. It's not like I'm going to be flashing cops as I drive by.

This is what I did. Except I used a inline fuse as the jumper and crimped on the tabs to plug into the slots. This makes it a little safer as the reg way will eventually burn out the jumper wire. Thats what happened to me before I used the inline fuse (amp rating is the same as the fog fuse under the dash). And I used very large gauge wire... The inline tucks nicely in the empty area to the left of the relays. Heres some pics...

I've been running my jumper for 3 years and never had a problem, but a fuse never hurts either.
