This is my first time working with relays, so I wanna double check all of this. Do I only need fuses on the wires going from the battery to the relay or do I need more?

Anything else wrong?

 

Looks okay at first look.
With the switches, you can run them all from one wire (short leads to jump to the next switch), and just fuse the one wire from the battery or wherever you're getting 12 volts, just to be safe.

 

Oh, and just another idea...
Use more DPST switches (on/off/on) for the other lights, and use a lead from the high beams... (on/off/on with high beams)
I also like to make lights switched either from parking lots, or ignition just so I can't accidentally leave them on.

 

Thats the way I have my fogs wired in that diagram. I also have it switched so they can be constantly on. I think I may run my KC's through a DPST swtich so I can have them with the highbeams or constantly on. It would be pretty easy just a few jumpers and call it good.

 

i thought you were going for the "clean look" with your truck and selling your KC's.

 

I have a light bar that slips into my front reciever. I got some different lights that are different.
