The plan that I want to give [to] you. Direct, Indirect object in attributive clause

I don't know the grammar rule I must apply in the following sentences. Do I need to add to?

1. Here is the book that I want to give [to] you.


2. Here is the plan that I want to give [to] you.


3. Here is the plan that I want to introduce [to] you.

The plan that I want to give you has already worked out for me.

Someone might think that the idea if the plan is to give listener away in exchange for something.
