Wrong plug to charger?

As the title states the plug that goes to the charger is the right plug in size but there is two bosses on the plug from the charger and on wiring harness is not made to fit them. Do I have a the wrong harness or do I have to modify the plug on the charger. All of the other plugs are accounted for and are plugged in. The charger is a He351ve. Thanks in advance.

Pics would help.................Tremendously

Called Fleece yesterday morning got it figured out. I had to modify the plug on the charger.
