PIAA 540 driving lights connected to OEM fog light switch and wiring????

Hello all. I have 04 Tj and I bought a set of PIAA 540 driving lights to replace the old factory ones. Wondering if anybody knows if I can just connect them to the factory harness and turn signal stalk switch. They came with harness and switch but would like to connect to OEM setup if at all possible. thanks.

I have 3 lights hooked up to my factory switch and no problem so far. Not saying I should have it this way but so far so good.

If they're 55w, it'll be Fine.

They'll be Brighter though if you Relay them. Even the Stock Fogs will be Brighter if you Relay them.

you should use a relay for all fog lights in my opinion. Constant from battery to relay and just use factory switch to activate relay coil. you'll have fewer problems, efficient power supply and just a safer more reliable set up. Just my humble opinion and your free to do what you like.
