I used the tundrapart.com kit. It's an easy install.
I wish our trucks were like the old ones with the dash mounted OEM switch. You can use your factory wiring, but you'd have to install a new turn signal stalk by pulling the airbag and wheel. No thanks.
I put the PIAA kit on mine. Do a search on PIAA on this forum and you'll find my post with step by step instructions and pictures. Not real hard to do. I would caution you that the kit is actually for driving lights and are required by law to be wired to cut off with High beams. Obviously, you can choose your chances. I actually thought I was getting fogs and suppose you could change out the bulbs but I liked the brightness so much I left it connected as directed. Good luck
