Where are y'all picking these up at and which models work on the grom?
is this direct plug n play or splicing required?
You want to purchase the Backoff XP
. The XP will work with the LED tail lights. It is splice in, but only need to cut one OEM wire (the switched +12V going to the brake light). You solder each end of the cut wire to the Red and Red White (If you like the 5 flash - solid pattern). Then connect the black to frame ground and your done.
Going from memory, the only wire on the Grom to cut is the Green/Yellow. Verify with a meter first. I poked a needle through the insulation to use my voltmeter without cutting to verify I was getting +12V only when the brakes are applied.

I didn't do a write up for the Grom. You can check my write up where I installed on my Versys here.
The only difference is locating which OEM wire to cut. Just substitute Green/Yellow (Grom) for Blue (Kawasaki Versys).
I placed it in the void where the tool kit belongs. Don't pay attention to the fuse and other wires in the photo below, that was taken when I ran 12V power to my socket at the handlebars.
EDIT: The location I chose required me to splice the 3 wires used on the Backoff XP to make them long enough to reach the cut Green/Yellow and frame ground (Shown in photo in yellow).
I found it cheapest on Ebay
this time. I ordered from this seller, and they shipped fast.
Good luck! It is a nice addition to any motorcycle. I would not own one without it. It does catch the drivers eyes behind you better than solid.
