The hardest part of a permanent install is running the fuel lines and modifying the tank. There is a bit of electrical work to alter the length of certain wires and remove circuits like starter. The tach input to the ecm needs a wire added with a ring terminal to connect to the coil - terminal (leave the orginal connector intact). This allows fuel only control which is not so hard to get going. Trying to do both fuel and spark control is tough especially if this is you first try at EFI.
