Yep, thats me! Did the same thing you did. Got pissed, fired up the soldering gun, and the rest is history.
Everything continues to work well from me. I followed my wife home from an ice cream date last week and she said that I am extremely visible with the fog lights or running lights on. She said that made her think how hard it is to see the bikes with just one light, in comparison.
Question for you --- how did you stuff your wiring back in behind the mirror? I cannot seem to get all those wires back into that small space, especially with the Kury connector, without a lot of hairpin bends in the wires. This worries me for the long term. I am wonder if I should put in some of those ... ummm... what are they called ... keep the wires straight near the connectors ... wire looms?? Anyway, do you have any advice on how to get those wires back so they aren't so bent and may possible break down the road?
