you said any help so there I go .  
I never installed an aftermarket wheel before but I know that 1 wire needs to be grounded to the hub ,the other wire will need to be connected to the horn . Circuit close when depressing the horn to make some noise .  
Try to determine which of these wire needs to be combine for the horn . Ground 1 of them and connect the other 1 to the center hub button .  
Hope that helps a little .
