Need wiring help on BB

[Alpha Crow]

Installing a mototek undertail, I'm at the final stage for wiring, but I'm not sure what to do. Mostly the instructions look like they were written by someone who doesn't speak english (shown below). Basically, I have 2 standard honda connectors, 1 for brake lights, 1 for running tail light. Each has a ground and two others (positive and negative, I assume?). The undertail has 3 LED bars for the rear lights, with 3 sets of wires (ground, running, braking) coming off of them.

"CONNECT SIGNAL AND TAIL LIGHT WIRES, WE ONLY USE ONE HONDA CONNECTOR TO CONNECT THE 2 MOTOTECK TAIL LIGHT, TAKE THE ONE THAT HAVE THE BIGGER GREEN WIRE, THE GREEN/GREY WIRE IS YOUR GROUND TO BE CONNECT ON MOTOTECK GROUND, AND CONNECT THE RUNNING AND BRAKE WIRE AFTER."

Question is how to I install it? They sent me a bunch of tiny connector ends for the wires. Do I cut the honda connectors off, wire the ground (which one, running or brake connector ground?) to the ground? Then the big question, which wires do I use for the running and braking from the honda connectors? Apparently some wires will not be used, but I can't figure it out.

Thanks for any help! Need to get back on the road again before the weather goes bad

Have you got a voltmeter ? If not it would be best to get one, turn the key "on" there is no need to crank engine, with the votlmeter locate the "running" wire it will read ~12v with the adjacent ground wire, after finding tag that wire.

Then depress brake handle search/test for anther ~ 12v wire be sure to retest everything to make sure everything is right (dont ask how I know this)

Grey wire coming off mototeck tail should be running lights,

Sorry if the info is insufficient just trying to help.
