Total lighting n00b questions

Hey TW

I did a little bit of searching but not as much as I normally do so forgive me if theres something obvious I missed.

I want to throw some fog lights on my taco and I've never messed with any of this stuff. I got my lights and my switch, but I guess I need to grab a harness? I dont know how I missed that.

Any really basic basic tips or tricks for wiring these up?

Also I popped out one of my dummy switches and found a connector on the other side. Not sure what it's for, any ideas?

 

Down Hill Assist switch...and NO, connecting the missing switch will not give the vehicle that feature...

 

Pop the other blanks, maybe the fog switch connector is there...(extreme left, on the inverter switch row)

 

Yeah I did a bit more googling and found what the blue connector was for. Also ended up picking up a harness and I can't believe I had to make this post. Looks stupidly easy to install. Sorry for the wasted bandwith!
