Trying to fix a charger

[Manofevil]

Some months ago I lost the seven hole socket off my bike’s charger. I just recently got the replacement part but I need to know how to wire it. I need to wire this plug to this wire.

you charger may have the wiring details on it. but if you put the plug omg the battery and use a volt meter to find the positive and negative poles you can hook it up .
