The driver side radiator connector is used to power the new radiator fan. You tap into the light blue wire on that connector. The passenger side isn’t used.
Good, I did this. I do have a connector close to the fuse box as the wiring video called for one there.As long as it is connected to that wire on the fuse box side, it doesn't really matter where. Of course this is a little higher amp draw, so you don't want to have a lot of unnecessary length, so it's better to splice at the fuse box.
I thought you tapped into the blue wire directly from the black connector in the fuse box? That's what the videos said to do.....
