2008 Mercury 25hp 4 stroke swap with 2002 9.9hp 4 stroke

[richinkentucky]

I am swapping motors on my pontoon, and upgrading from a 2002 Mercury 9.9 4 stroke to a 2008 25hp 4 stroke efi with power tilt and trim. My question is which wiring adapter do I need? Will the controls I have work?

Shouldn't be any problem.
