Wiring changes to make one motor run clockwise while the other runs counter clockwise.

I am currently applying the finishing touches to a motor system for a 41' sailboat. I have installed two brushless etek engines on a dual input single output 1" browning gearbox. Because of the gear box one motor will need to run clockwise while the other is running counter clockwise. I am using two Kelley KBL 24201 controllers and the Kelley control box. On the advise of Kelley I have brought a connection from the other side of the reversing on off on switch to the controller #2. When controller #1 reversing wire #9 is open controller #2 reversing wire #9 is closed.
