Dont tap, you'd want a dedicated circuit. You have a fuse box under the hood for load power, and a fuse block at the driver's door for switch power. Use a relay and boom, perfection.

I’m not great with wiring. Would you mind a brief write up on how the boom perfection happens. I was planning on running a wording harness from the battery to the lights and they the firewall with a switch under the cluster. I would like to be able to have my lights come on with my high beams.
light bar negative to ground
light bar positive to relay
relay positive to battery (with inline fuse)
relay negative to ground
relay trigger to high beam positive

if you need a picture of how it would wire up to the pins on a relay just google something like "fog light relay wiring diagram" you will get a ton of results but there will be diagram photos showing which pins are what on a standard relay. any type of aux equipment will wire up the exact same way
I have both of my HID headlights wired the same way it takes the strain off of the factory wiring, the headlight positive wire is the trigger effectively taking all amperage off the factory wiring

yep, I have done this on others and plan on doing this to my current Tahoe, in almost the same mannor, as I have on my car. and as noted wes's description is about as simple as it gets.
