Tl Smoother problem to connector

Hi guys.
I buy this:

I cant connect it due a different connector size
My motor connector pin is more small and have 6 pin ( but only 4 is wired)
How can i do for connect smoother to each motor?

I've to create diy adapter?
I try to unplug wires from original connector and insert it in the smoother connector,but the original have a too small holes,and "dance" inside
