LGB & Aristo OnBoard

New to the forum. I have been “listening in” for about a year and have learned a great deal. Now I need specific help. I have an LGB engine from a starter set. It claims to be decoder ready on the bottom of the engine. Can I take and install the Aristo 75 MHZ on board reciever directly into this engine? If so, is it a simple plug as in an aristo engine. I have done that so feel I could be competent to install if the same is true for this LGB engine. Thanks for any help.
