The first one should work:

EVENT_MANAGER:RegisterForEvent("HarvestMap", EVENT_ADD_ON_LOADED, function (eventCode,addOnName)
    if addOnName == "HarvestMap" then
        Initialize()
        Harvest.OnLoad(eventCode, addOnName)
    end
end)

Basically you're only passing a reference to the RegisterForEvent() method, it doesn't *require* a name for the function.. and you definitely don't want to re-define Harvest.OnLoad() if you want it to call the other one inside the reference.

Looking good tho!
