Default Underhood Accessory (switched) Power UGH!

I've been searching like crazy, but no dice.

I put a set of lights on my brush guard, and I need a switched power source for the relay, but I'm hoping for something under the hood. I know I could run around with a multimeter, but without unwrapped a ton of wires, I'd have to start piercing them, and I don't wanna do that.

I tried the age old GM theory of 'the yellow wires are acc wires' but I came up short. I also know of a couple wires under the dash that I can tap in to, but I'm keeping that as a last resort (already ran 2 wires through the firewall and hated it - not looking to run a third)

If anyone knows wire colors/locations or has a diagram of the engine bay, I would really appreciate it.

As I stated, I've been searching the forum a ton, and only finding answers for wires under the dash - not under the hood. But thanks for the helpful insight.

Did what I was too lazy to do in the first place... Got under the hood with a multi meter and found the right spot to tap. Thanks for the views!
