I bought the harness but looking back I kinda think I should've just soldered the wires and saved $75 (3 harnesses). That's why I'm telling you it can be soldered, it's kind of a PITA but $23 cheaper per switch.
I was originally going to connect little spade connectors to each terminal but the terminals are so close that I'm pretty sure the terminals would touch.
This isn't the light switch, it is a VSC switch but it's the same just fewer terminals. I soldered leads to this one.
you can see the terminals better in this pic with the switches taken apart. The one on the left is an FJ switch, the one on the right is the VSC switch before I soldered the leads on.
Here's a shot showing my JAOS brush guard. It was on it when I bought it, otherwise there's no way I would have spent the $1,400 bucks for it. I've seen a few on 4Runners around here that I didn't like, but I like mine. Definitely don't think it's ghey.
