Bumping this again... finally decided to start digging in on this.
I was able to find the wires I needed in the bundle behind the kick panel on the floor of the passenger side. White/yellow for right turn, white/dark green for left turn, and found a black/white that was a good ground...
Problem is that when I tested them, the LED pattern is screwed up. Instead of going top and bottom of the first arrow, then top and bottom of the second arrow, then finally top and bottom of the third arrow... mine are zig-zagging for some reason. So they go bottom of the first arrow, then top of the second arrow, then bottom of the third arrow. ??? The opposite side that isn't lighting up actually faintly lights just a little bit, but nothing like the bright LED's on the opposite side of them. I tried both turn signals I have and I tried tapping them into both sides of signals coming from the car... and regardless, I get the zig-zag pattern.
Might be hard to tell in the video, but here is the weird pattern...
Any advice? Do I have a bad set? (if only one was doing it then maybe, but it's hard to believe that both are faulty in the exact same way)
Or I'm thinking maybe they need some sort of resistor? They aren't causing my front and rear turn signals to hyperflash or do anything different, so I'm not sure if that's it either.
Any help is greatly appreciated. I'm certainly going to wait to install them in my mirrors until I can get them to test properly first.
