Can someone check my wiring homework?

I’m a total noob at automotive wiring and was wondering if someone could double-check my plan and offer any suggestions before I start messing around in there and screw something up.

Here is my situation:
I have a 2010 Prius with no factory foglight so I purchased

2010-11 Toyota Prius High Power LED Fog Lights Assembly Kit w/ Wiring




and I also wanted to swap out my turn signals so I purchased

I want the fogs to turn on/off with the switch that is included in the kit so I plan to install that as shown in the diagram



Seems pretty straightforward up to here (knock on wood).


Here’s where i’m not so sure…

When trying to hook up the DRL/indicator, I the indicator part is supposed to be PnP, but I need to tap the DRL part into a circuit.


The lights came with parts to tap whatever wire, but I want to be able to turn the DRLs off with a switch so I purchased this
switch:

TOYOTA LEXUS SCION LED DRL Daytime running light special SWITCH control | eBay

and
harness/relay:

HID Conversion Kit Wire | HID Relay Kit | HID H11 880 Relay Harness Wiring

and I’m planning on hooking the DRL up just like the instructions for the foglights, but i’m not sure which fuse I should connect the DRL to the fuse box. I do have one of these and was planning on using it, but not sure which fuse is best to piggy back off.

Low profile fuse tap:

The other question I have is, based on the foglight instructions, it says to tap the switch into the brown wire of the ECU.


What wire is that for? Should I tap the same wire for the DRL on/off switch? Is that ok or is there another one I should use?

If someone could let me know if this plan is ok or if there is some fatal flaw in it, I would really appreciate it.
Thanks in advance for your help!!
