No the antigravity pigtail would have to be mounted on the bike, directly to to the positive post of the battery or at the starter post.

Saw a guy on a Heritage at a bike rally years back....he had a coffee pot he'd use in the AM, plugged it into the battery somehow.
Sure enough on Sunday guys bike wouldn't start. But hey, he had coffee lol.

By the way you can't push start a fuel injected bike with a dead battery but you can push start one with a battery that's too low to turn over the starter but still has some juice left. Often a battery that's too low on amperage for the starter motor may still read 12 volts. The ECM and fuel pump only need a fraction of the amperage that the starter motor requires.
I know this because shorty after I argued with a friend about it and told him it wouldn't work he pushed his bike down my steep driveway and started it up before he hit the street.

Dont try to reverse feed the OEM pigtail coming from the battery. There was a thread about this a little while back where someone tried it and fried a few things, more than just burning the pigtail wiring.

You would not be able to use the factory pigtail. The wiring is too small as is the fuse. It would certainly be easy enough to make one yourself though. Some good, heavy guage wire and a connector suitable to carry the current. If you know someone into electric remote control they would likely have everything you need.
Or you could go with tge system above...

New guy here. I have one of those Antigravity Micro-start jump-starters which has saved me many times. You'll most likely need one harness for a jump-starting device and one SAE harness for your charging device. Most of the time, having one wire for both won't work because either the gauge is too small or there is a component on the harness which prevents usage of both devices.
