I have this booster and it works well for me. I left the charger cord on the battery and added the booster cable to the battery. Pretty hard to screw this up if you're paying half attention to what your doing. No need for and added dongle, both cables fit fine.

Yup, a simple check with a multi-meter will allow you to see that the polarity is indeed reversed. It's not a mistake either, the company did this intentionally as the circuit protection they utilize won't allow for the pigtail to work with normal polarity. I tried quite a few different setups. Even reversing the leads won't work because the circuitry built in is all screwed up.

I know that if it has **** or wheels sooner or later you are gonna have problem but ever since AGM batteries I have never needed one .....yet. Once recently a riding buddy had his go dead, turned out to be loose terminals and after tightening we bump started it, luckily there was a short hill !!
Are a lot of you having issues with dead batteries??

I have the Anti Gravity cable and it works, but not properly. Also it could be a bit longer, at least on touring bikes.
My tender continues to blink red (as though it's still charging) even tho when I check the charge it's at 14.1v.
When it's convenient I will put the tender cable back on and use both.

Well got myself a month ago the latest Antigravity XP-1 for the ride just in case, and guess what, left my Toyota van outside for 3 weeks in -12 Celsius temps, and battery would not start the 2.5 diesel engine, so I put the little XP-1 on the battery and the van fired up in a second, so this will easily fire up a Harley, I got the pigtail also, but have not installed it in ride yet.

Bob,
with the load of a duff battery, and lights ( leds use much less power) and the normal load of a running motorcycle, the output rating of the charging system can be exceeded.
this can destroy the stator and or the voltage regulator.
a $100 battery problem becomes a $600 charging system problem ( +the battery).
The result of jumping a harley may be costly.
so what do you do...?
I have roadside with unlimited mileage to the nearest dealer...in the US/CA it's a $20 add on to HOG
Or being fairly savvy about electricity- pull the lighting fuse or relay to kill the lights...conventional lights are probably the biggest load on the system...lights off, radio off, anything you can leave off...
and making sure that you aren't riding around with failing or worn stuff...batteries, fluids, tires etc

I guess I'd better check the pigtail on mine to see if it's polarity is reversed, as I did install their harness on my SG. If I have to, I'll build a new harness myself. FYI, the XP-1 uses what's called an EC-5 connector (the blue plug).
