I am going to install 3 light bars on the front of my truck. 2017 F250

1 x 20" Rough Country 120 watt
https://www.roughcountry.com/20-inch-led-light-bar-70920drl.html

2 x curved LED spot lights in the grill.
210W Spot 43.3 inch 45.2" 3D Mini Curved Single Row Led Light Bar Cree 5W Led Driving Working Offroad Light Auto SUV Barra Car Jeep 4WD UTV Truck Pickup 4x4 Vehicle 12v 24V Wire Harness https://www.amazon.com/dp/B01N4L93HF/ref=cm_sw_r_cp_apa_i_py6gEb9FH7VRR

I would like to use #6 upfitter switch.

2 questions, can all the lights be wore to the same upfitter switch? And do I use the provided wiring that came with all the lights? I know I don't need the relays. How to I modify the harness' to connect to the upfitter switches? Am I on the right track?

Thanks for the help!

Upfitter switches 5 and 6 are fused at 40A... 12V at 40A = 480W, 14V at 40A = 560W
120W + 210W + 210W = 540W. Good design practice would have the circuit operating at 75-80% of the fused value.
Separate the 20" light bar operation from the by using an additional upfitter switch.
Or use the wiring provided with the light bar, and have the upfitter #6 switch trigger the relay operating the light bar.

Thanks, I think I will use the relays instead of using up 2 ipfitter switches.

Each switch from the light harness has 3 wires, I would just connect the upfitter switch to one of those three wires and tape off the other 2?

The Rough Country light bar has two circuits. One is a low powered DRL type output, the other is the 120W of LEDs. Hard to tell what is provided in terms of wiring with the pictures and instructions on their website. Doesn't describe wiring as having a relay or not. Wouldn't be hard to add though.
