The Proton front signals are pretty nice. I have them myself.
To make the install easier, look for a wiring kit that has Honda OEM style connectors.
Then you wire the Protons to the kit connectors and they just click into place. No muss, no fuss.
I can't offhand remember the brand, but I found them at Cycle Gear.
For the Hotbodies undertail, don't follow their instructions and chop off the fender past the battery box.
That totally screws up the undertail fitment and causes the undertail to flap in the breeze.
Instead, trim the fender in a square 'U', thus keeping the rear fender support and relay mount posts.
Search on the site and you'll find some photos I posted on how I did mine.
I also used some scrap from the removed fender portion to fabricate some additional support tabs to further support the undertail.
That baby is solidly mounted now.
If you need more photos, let me know.
