I did do up fitter switches which definitely added a lot of time to the process.
I have 2 things to note. First was I made the holes you drill way bigger and out much farther to the edge of the grill, otherwise the wires still got pinched. It wasn't a big deal but after drilling a single hole in what looked like about the exact same spot as your video, there was no way it'd sit flat, so I had to extend it out so the wires had room. Not a big deal, and an easy fix.
My other issue and I might just not understand the route you did, but on the passenger side, if I mounted the box behind the headlight, there was absolutely no way the connection from the grill light would ever reach the connector to the little box. I pondered that over a beer, and ended up relocating the little box to under a painted section of the engine bay, up higher than it'd be on the headlight and giving me tons of slack.
You've obviously done it so I assume it can be done, but there was no way my hands could ever make that connection. I'm really happy with where I put it, I think it'll hold, I'll keep an eye on it.
On future builds I'd add more wire to the grill section and the controller box. It's easy to stuff excess wires somewhere but not having enough is a little frustrating. I'm talking just the ends with the connectors. I could have extended them myself, but I was at the point of the grill being back on and I hate splicing wires if it's not necessary.
I hope that wall of text doesn't seem like a complaint, just sharing my experience. I'd buy them again in a heartbeat. 100% satisfied!
Edit: yes, my DRL's are at 60%, i was surprised and very pleased with how bright the Putco emblem and your grill lights are. I swear they match the 60% perfectly.
