Just flip the fuse box over and find the black low amperage side of the relay that turns the headlight on and off. Clip the black wire and carry it to a switch. Then from the switch go back and feed the other side of the wire you cut. In the third picture im holding the yellow and small black wire from the correct relay. Just clip that small black wire so that you have enough slack to connect a wire to the ends of both sides of it.
Pretty simple. Just had to look at the fuse block and the schematic for a few minutes.
I better get a "like" or "informative" on this post. Lol
I wanted to add something to this. Don't let this confuse anyone::: All your doing is completing the ground to turn on that relay. Technically (and I don't know why this wouldn't work) you could just run the wire down from the side that feeds the relay to the switch. Then from the other side of the switch go to a chassis ground. Then when you flip the switch it just grounds the wire and the lights come on.
This is what I made up to do the job. I even threw in a spare yellow wire for the future.
P.S. Someone brought it to my attention that the NEW headlight recall was a bit different. From what I understand it uses two relays to run all the headlights. If that is true then all you have to do is break both ground to the relays. No biggie. You should be able to use the same wire that you ran to the switch and just connect it to both relays...
