I know I've seen it somewhere here but can't find it now. I am wanting to hook-up my driving lights to turn on with my high beams but also want to be able to turn them on separately without using the highbeams. Can someone point me in a direction? Thanks!

Get a five pin Bosch relay. Pin 86 goes to your aux switch. Pin 85 goes to ground. Pin 87 goes to battery for the new lights. Pin 87a goes to the high beam wires. Pin 30 goes to the driving lights.

I used a Single Pole Double Throw (SPDT) switch to produce a similar set up on my bed lights.

Center terminal goes to the lights, one side comes from a constant 12V source, the other side comes from the overhead lights. I can select "on" at any time using the constant feed, "switched" which will turn them on and off with the cargo lights, and "off" which which is self explanatory.

Using a relay to pull power from the battery is a good idea, but I was only powering some LED strips so I didn't want to mess with the additional wiring.

How about running your driving light directly with your highbeam and then run a diode in line with the driving light to a switch?
