My experience with the Admore Givi kits is mixed.
I got a set for the Missus' NC700XDCT, her first "big" bike, which came with Honda OEM luggage. The Admore kit was the recommended one.
Turns out I was sent a bad "processor", the electronic control that sorts the various signals and sends them to the trunk LEDs. They first insisted I'd wired it wrong but eventually sent a replacement.
The results were underwhelming once I got it to work. In daylight, I felt it was of minimal value. In the dark it did help but wasn't bright enough to be distracting, which is sort of my personal baseline for rear lighting.
Then came my FJR with the E55 Maxia and with Admores inside. Problem was, the dealer's boys were a little too energetic cleaning up the farkles and removed both the bike harness part and the trunk harness, while ignoring the LEDs inside the lens. About $110 worth of parts, that I hesitated to buy.
Along the way, in the Other forum, a guy did a thing about fabricating the controller, a pair of diodes and a resistor, one set per light. I just made up one set and used it to make running and brake lights out of the trunk's LEDs and ignored the turn signal function. I had not been impressed by it anyway on the other bike.
After that, I discovered you can buy some pretty decent LEDs on Ebay at cheap prices, so I ordered a variety and started goofing around with them. I had an old E50 Maxia and ran some strings back and forth under the lens- I'd owned the thing for a couple of decades and never really understood it was made to have lighting in it- and produced a pretty darn nice setup.
I added a couple of strings to the NC's outfit that helped quite a bit.
Soon every trunk in the place was was getting LED-ed up and I never gave another thought to aftermarket kits.
I looked around and can't find that forum link with that fellow's wiring diagram. I will have to look further.
