Yes it does! The video i saw had the guy cutting the little nib completely off and then sealing it with some clear sealant/caulk. But you're right -- if the wires are small enough (which i think they are) it should fit with a minimal cut.

Wondering how easy it was for people to feed the light bar switch into the cabin. I've seen videos where they had to drill into this rubber grommet. Looks like a pain! How did you all get the switch in there nicely?? Sent from my Pixel 2 XL using Tapatalk
