What wiring harness do i need for the nilight 18024c-a 420w 20inch triple row flood spot combo 42000lm bar? i have one for 120w but the bar is 420w?

First, for what its worth, this unit does not provide 420 watts of lighting, it is closer to 200. However, if it did use 420 watts, it would draw a tiny bit over 30 amps when your vehicle was running (13.8VDC is the "normal" voltage your alternator will provide). If your vehicle was turned off, it's battery voltage would probably be around 12.5VDC at first, and then it would draw around 33.5 amps. Long answer, but if you use 10 gauge wire with this unit you will be fine. I am actually using much smaller wire on mine with no issues, but am a bit scared to recommend someone else doing so (I am using 14 gauge as my unit is only pulling 15 amps). By the way, Watts divided by voltage will give you the amperage on a DC system for most applications).

Does the Nilight 18024C-A come with a wire harness and switch?

No. If you scroll down to the things bought together you should see this ... Nilight - NI -WA 06 LED Light Bar Wiring Harness Kit
