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.

They're all over the internet. For me, this is a must have mod. I just put one on my Grom. I also have them on 4 other bikes. :smile:

Ok I can't figure this out

i did it like stated and it's not working
Be more specific. Brake light does not light at all or does flash?

Check the Black wire to frame ground. Check that you plugged the brake connector back in (if you unplugged). Did you verify that the wire you cut Green/Yellow was the switched 12V? Are you positive you connected the correct green/yellow to the correct color wires from the XP? If you reversed them, it will not work.

You spliced the XP black wire into black grom wire??? I just looked at the wiring schematic in the maintenance manual and I believe that it your problem. Run the XP black wire to frame ground. Run it under a bolt that is threaded into the metal frame. I used a ring terminal and connected the black XP to the frame in front of the battery. There are two bolts just behind the gas tank. One of them has a bunch of ground wires coming to it. I used the other bolt.

Verify XP red/wht stripe is connected to the wire coming from the LED Lights end and the XP Red wire is connected to the wire coming from the front of the bike end. If these are reversed, it will not work.
