Finally Wiring Up My GT/CS Fog Lights - Need some help (relays)

[DirtyD]

So hopefully this weekend, weather pending, I will finally get around to wiring up my GT/CS fog lights on my 2013 that I installed over a year ago. :burn:

With that said, I have the idea on how I was to wire everything up, but I'm in need of a little help getting everything layed out correctly with the relays.

Overview of how I want the setup to function:

1) Grill lights will turn on at the same time as the LED DRL strips in the headlights.
2) Grill lights will then remain on with headlights turned on (both manually and Auto mode), and also stay illuminated when high beams are engaged.
3) When the MFS (multifunction switch) is pulled out to turn on the GT/CS fog lights, I want the grill lights to switch off and the fog lights to now illuminate.
4) When high beams are engaged WHILE fog lights are on, I want the GT/CS fog lights to shut off as fog light due when the high beams are engaged, and I want grill lights to illuminate again, taking their place.

The GT/CS fog lights will be tied into the existing fog light circuit

I figured out that I will only need 1 relay, a 5 pin ISO style for each circuit afterall. All negative leads will go to a chassis ground as well.

Here is what I came up with using as far as the diagram goes. Does anyone think I will have a problem using the "+" wire from the DLR strips as my constant power wire?
