Splicing new Evinrude controls to pre 96' cable

[Curapa]

I have a pontoon boat with an 80's Evinrude 115 and I need new controls. I'm trying to avoid buying the new cable/adapter and i'd like splice the new 96+ controls in. I don't have a system check gauge so no issue there.

Can this be done? I realize the wires are not color matched. But it seems doable.

Thanks,
