pulling the engine
 

Hello all,
I am new here to the forum and I hope to get some great info here. I do have a question already that I hope you can help me with.
Not to sound blasphemous, but I have a 1994 Miata that I want to pull the engine and computer out to install in my 1973 beetle. Can anyone tell me what electronics do I need on the motor and wiring harness as well as the comp.? ( and by the way I am saving the Miata for a special upgrade down the line)
