i want to be able to turn the fog light on/off and plan to order this harness on eBay. Figure I place the on/off switch somewhere in the frunk worst case. Can you take a look at it, any issues? I think it should work.

hard to tell from pics but looks like a bunch of it is not needed, might work but have to tweak it a bit.
On my diagram you could just put a switch between the wire coming off of 85 or 86 to do same thing
