Yes, it was relatively easy as far as mods go. No, there was no change to the front flashers with this unit. I recently put LED switchbacks up front. That was also easy and is a big improvement over stock. I think I posted about it earlier in this thread. Same/similar Kuryakyn bezels as in the rear. I got the switchbacks from Goheen Cycles. Only pointer I have is be sure to get the flasher/relay for LED lights. You only need one per bike-front and/or rear will work the way they should when you switch it out. Also be sure to get clear lenses for the front and red lenses for the rear if you go with a similar setup to mine. The front switchbacks have a white running light, and amber turns. The rear legally has to be red if it’s a running light, and can be either amber or red for turns. Therefore the red lenses work perfectly with just a white LED bulb. And I agree, this should be stock from the factory, but I guess they figure most people will want to mod the way they want it, and so they don’t waste the money. Hope this helps. Enjoy your ride...
One other thing I forgot, the Custom Dynamics unit comes with Posi-tap and Posi-lock connectors. They are small in themselves, but taken together they take up a lot of space. Put some thought into how they will sit after installation so the rear fender will rest all the way down like it should. Not hard, but does require a little forthought. I didn’t even zip tie the unit down because there is nowhere for it to go. It’s perfectly wedged into the small space left by the stock harness and plugs. Have fun.
