High Beam + Signal?

[rdsaustintx]

Hey there,

 

Noob here. Enjoying lurking, especially motomedic and the diode tricks. I have a '14 Z71

 

Here's my question, have looked all over but can't find a good answer:

 

I am installing PIAA driving lights, want them on with high beams. Where can I pick up +12V for relay trigger, either under hood or in dash?

 

I could use ground trigger, but the light kit comes with a wiring harness configured for positive trigger, would be much easier if I could just find +12V for high beams, preferably without tapping into the lighting harness.

 

Thanks,
