PIAA light install question

I know this topic has been covered, but I'm a little confused and just looking for some confirmation. I have an '08 Sahara Unlimited and just purchased a set of PIAA 520's. Is this the proper configuration to have the lights work independently from the main driving lights and fog lights??

PIAA wiring harness attaches to battery and new lamps, supplied wired switch for turning on/off runs off of harness and into cabin via firewall, power from fuse box, off of M8 (via add-a-circuit, 10amp) to on/off switch, mount switch in desired location.

I was reading about an inline fuse but since the supplied relay has one, is this needed?

Any help is greatly appreciated!!

I'm a little confused by your description. So...

It is a good idea to have the switch activate a relay. The relay in turn turns the lights on and off. Power from the battery (with a fuse of some sort) to the relay, from the relay to the lights. the relay can be activated by the switch or it can be activated by another circuit, like the factory fog lights. This way all the higher amperage wiring can stay under the hood and out of the cabin.

I don't know the legality of having however many lights on at one time, but this is the reason the factory fog lights turn off when you use the high beams.

Determination: the feeling you get right before you do something incredibly stupid.

The supplied switch I referenced I believe turns the relay on and off.

I could be wrong, but I believe the PIAA 520 series is intended for off-road use only. So having them work independently of your normal road lights is the way to go.

Your lights should have come complete with everything (wiring harness, inline fuse, etc) you need to simply hook em up to the battery and go.
