your question has been answered but here is my opinion on relays:
Determining the need for a relay (for me at least) revolves around the length of use and power required.
For example... i relayed the aftermarket fogs on my PJ bumper to my factory fog switch --> they are on for extended periods of time.
My windshield lights are not relayed b/c they are used as follows:
a) off-road for periods less than two hours***
b) momentarily to advise the dumb as in front of me that he/she is incapable of managing a motorized vehicle and thus should remove himself from the road.
The switch heats up noticeably for extended periods... but no problems thus far.

I'm in the process of wiring up a pair of Hella 500's using the harness & relay that came with the kit. I was about to wire up the switch last night when the instructions called for me to tap in to the high beam wire. Like so:
I hadn't really thought about it up to this point, but is this going to limit when my Hella's will turn on (whether my hi beams are on or not)? I want the Hella's to work independently of my hi/low beams and factory fogs. If this will limit when the Hella's turn on, do I need to skip the relay? Like so:

If connected correctly
Less current on switch = smaller wires in cab area.
More current to lights = Much brighter lights.
All high current wiring stays under hood ie. Larger wires.
Also the ability to connect switched wire to park lights/lighter/switched hot/ high beam /low beam wires with out issues.
All ways use fuses as close to the source of power there’s no excuse for no fuse I have seen sever damage from this any length of UN fused wire from the battery if a short occurs you have instant fire.
An indicator light is also a nice, especially if you have light covers.
Be safe hope this helps

i would keep the relays in, and hook up to a keyed source, so that way you can shut off the power, incase of a relay issue, or a switch that gets wet shorts and turns on.....had a water issue with my tj, and ran battery down, it had duel batteries, luckly the batteries died, before the loom had a complete meltdown....
but check with you local laws, some place will not let ya pass inspection unless the fogs turn off with the highbeams??
by the way that was a nice rack....are they cold they were blue
