Power trim n tilt

[imported_Newt]

I own a 1987 Johnson 110 hp outboard. However, it does not have power trim. Never did. I found a used unit on E-Bay and am tempted to buy it, but I don't know how to install same.

Does anyone know a website where I can get information on this ? Perhaps instructions so I'll have a clue what I'm thinking about taking on.
